Post your ideas for new math programs here, or build on ideas posted by other visitors.

I would like someone to make a math program for numerical analysis for advanced math classes. I do know this would be an easy program to make, although, I need to know how to start it and if someone could show me how to start it, I could make one and then put it on the site. I have a TI-83 or TI-92 Plus. So if you have any ideas, contact me asap.

Hey. So what kind of Advanced Math Classes are we talking here? I could help but I would need equations on what you are talking about then, I could send you the information you want and need to get started then you could do the rest.

Can I get some help on a midpoint and a distance formula

What calc?

He said he has a 83+ or 92

like what? just use prompt, variables, and the correct equations too. right?

If You are looking for distance formula, and have a ti-89 then you could download mathwiz.
It has a program in it which figures out the distance, midpoint, slope, and the y-intercept formula for the line. All you do is type in two coordinates and everything else is done. Anything else?

simple

DISTANCE
prompt A,B,C,D
disp (sqrt((A-C)^2-(B-D)^2))

MIDPOINT
prompt A,B,C,D
disp (A-C)/2-(B-D)/2

another option, with both formulas in one BASIC program for the ti-83+

Prompt L1,L2
Menu( "welcome", "midpoint",MP, "distance", DI, "exit",X)
Lbl MP
DelVar L3
(L1(1)+L2(1))/2 -> L3(1)
(L1(2)+L2(1))/2 -> L3(2)
Disp L3
Stop
Lbl DI
sqrt( (L1(1)-L2(1))^2 + (L1(2)-L2(2))^2) ->D
ClrHome
Output( 1,1,D)
Output( 2,1,"sqrt(")
Output( 2,3,D^2)
Stop
Lbl X
Stop

It may be a bit long, but it gets the job done well.
Note: the spaces are not part of the program

I tried using the program you suggested and all i recieved were errors. It is most likely my fault but there are symbols that are close to the ones you typed that confused me if it isn't too much trouble would you please specify how to type each character. It will most likely will be a pain but would be greatly appreciated
Thank you for your time

the symbols are:
sqrt= the square root button.
L1-L2= list one and list two
^2= is the the number squared.
->= is the sto-> button
if you need it, i could write it for you.
ill email it to you if you need it.

Here it the program I wrote for slope, midpoint, and distance. not that yours wont work, i just think that mine is a little easier to understand for beginners. it is as follows:
:disp "(x,y),(a,b)"
:prompt X,Y,A,B
:B-Y->C
:A-X->D
:if D=0
:then
:disp "NO SLOPE"
:Else
:Disp "SLOPE"
:Disp C/D ->frac
:End
:sqrt(C^2+D^2)->E
:Disp "DISTANCE",E ->frac
:((X+A)/2)->F
:((B+Y)/2)->G
:Disp "MIDPOINT (X,Y)",F,G

Thats all there is to it

P.S-
->frac displays the anwser as a fraction, it is found under Math:1
also, just so you under stand the program asks for two points, that is the (X,Y),(A,B)
if you type in the point and it displays "NO SLOPE", this is if the line is verticle and the slope involves dividing by zero.

Seriously, don't be a butt.

You say he never assigned R a value, and that you can't just 'store' something ( sqrt(X^2+Y^2)-> )
Using basic problem solving skills, i bet you he meant to say:
sqrt(X^2+Y^2)->R

I know, big leap right?
Anyway, how to TRULY write a slope/midpoint/distance program:

ClrHome
Disp "(A,B) (C,D)
Prompt A,B,C,D
D-B->X
C-A
Disp "DISTANCE",R>Pr(X,Ans
Disp "MIDPOINT", {(C+A)/2,(B+D)/2
If Ans:Then
Disp "SLOPE",X/Ans
Else
"NO SLOPE

That, ladies and gentleman, is the most optimized for memory program you will find.
If you are uncertain what R>Pr is, it is #5 under [2nd][APPS] or the ANGLE menu.

I think you replied to the wrong comment, because putting it here doesn't make any sense

:Input "X=1",A
:Input "Y=1",B
:Input "X=2",C
:Input "Y=2",D
:C-A->X
:D-B->Y
:sqrt(X^2+Y^2)->
:ClrHome
:Disp "DISTANCE IS"
:Disp R
:Disp "MIDPOINT IS"
:(C+A)/2->X
:(B+D)/2->Y
:Disp {X,Y}
:Disp "SLOPE IS"
:if (C-A)=0
:Goto 1
:(D-B)/(C-A)->
:Disp S->Frac
:Stop
:Lbl 1
:Disp "THE SLOPE IS","UNDEFINED"

Wait a minute. What's R? You never assigned R a value. And sqrt(X^2+Y^2)->? You can't just store a value. You have to store it into something. Also the "stop" is not needed at all-you hadn't yet used Lbl. Anyway, you don't need to use the Goto function in the first place, and should avoid using it--it's just sloppy coding and can lead to lots of syntax errors in longer programs.

I think the stop is needed here, otherwise the message would appear even if it isn't supposed to come.

That's correct. Without the stop, it would tell you the slope then inform you that the slope really doesn't exist... also, the goto part is fine... it could be replaced with if then else, but that would be more memory consuming. True, long programs may be confusing with thousands of gotos, but they are generally less efficient if other methods are used.

Sorry, did you say if-then-else is more memory consuming than a lbl statement and a goto statement?

Consider:

:if (C-A)=0
:Goto 1
:(D-B)/(C-A)->
:Disp S->Frac
:Stop
:Lbl 1
:Disp "THE SLOPE IS","UNDEFINED"

//label and goto

:if (C-A)=0
:Then
:(D-B)/(C-A)->
:Disp S->Frac
:Stop
:Else
:Disp "THE SLOPE IS","UNDEFINED"

// if then else.

Dude, all you need to get MP and DI is the same 4 prompts.
So:
::"DIST
:ClrHome
:Prompt X,Y,Z,T
:(Write your own formulas, I have a science fair project I should be working on... Find both DI and MP with them.)
:round(D,5)->D
:round(M,5)->M
:Disp D,M
:Pausde
:End

Gets the job done nicely, not pretty, but efficient. You can even cut out the round func and make a cool
:Output(5,1,"Distance:")
:Output(5,11,D)
:--- Same thing on the next line for Midpoint

You could do slope with it too.

How do you get = sign on calc for...
:if D=0
send to bboy623@gmail.com

you press 2nd MATH and enter

Converting to a fraction won't work so well if you take the square root of a number. You won't get a fraction-just an irrational number. Other than that it seems good, once you save a few bytes.

I know how to program inside the calculator, but how do you program in the computer? do you use Ti sdk? or can I write the program in c or java and than transfer it to the calculator? thank you

I personally use TI Program Editor. It's perfect.

So it would look sort of like this

:Prompt L₁,L₂
:Menu("WELCOME", "MIDPOINT",MP, "DISTANCE",DI, "EXIT",X)
:Lbl MP
:DelVar L₃
:(L₁(1)+L₂(1))/2 → L3(1)
:(L₁(2)+L₂(1))/2 → L3(2)
:Disp L₃
:Stop
:Lbl DI
:√( (L₁(1)-L₂(1))²+(L₁(2)-L₂(2))²) → D
:ClrHome
:Output( 1,1,D)
:Output( 2,1,"√(")
:Output( 2,3,D²)
:Stop
:Lbl X
:Stop

I have input this program and it doesn't work.

I made a version that outputs it to the Ans variable a few days ago.

Input "X1: ",A
Input "Y1: ",B
Input "X2: ",C
Input "Y2: ",D
sqrt((A-C)^2+(B-D)^2) -> Z
Disp "DISTANCE:"
Z

i was looking at this and i noticed that the formula was wrong and that it should be the sqrt (a minus c)^2 + (b minus d)^2

I like this one, but most teachers want an exact answer, so I leave out the �� out and then write it in radical form.

:I'm not saying anyones ideas here are not the best way to go about this program,but i made one without having to input A,B,C,or D more than once. After typing in the X and Y values it will display The distance, and when you press enter it displays the Mid-point, and finally with another press of the enter button it will display the slope as well. (MADE ON TI 84+)

Lbl A
Prompt A,B,C,D
Sqrt((B-A)^2+(D-C)^2)->A
((A+B)/2)->B
((C+D)/2)->C
(D-C)/(B-A)->D
ClrHome
Disp "DISTANCE"
Disp A
Pause
ClrHome
Disp "MID POINT"
Disp B,C
Pause
ClrHome
Disp "SLOPE"
Disp D
Goto 1 (NOTE:The goto 1 is referring to another part of the larger program itself and if you made this by itself i would have it go to Lbl A.)

Now this is what I'm talking about!!! Perfect! Under 450b / RAM I bet and works for sure. A bit excessive on the paranthesis, but it's a good way to find bugs in programs quickly.

Alright. 450 mb? blow your mind:

*R>Pr is located under [2nd][APPS]

ClrHome
Disp "(A,B) (C,D)
Prompt A,B,C,D
D-B->E
C-A
Disp "DISTANCE",R>Pr(E,Ans
Disp "MID PT",(C+A)/2,(D+B)/2
If Ans:Then
Disp "SLOPE
Pause E/Ans
Else
Pause "NO SLOPE

This is 125Mb maximum, depending on the length of the program title.

Why not display the results all at once?

i wrote one that displays all the results at once...its a bit lenghty but it works

Disp "Distance=1st"
Disp "midpoint=2nd"
Disp "Slope-3rd"
Disp "X1=?"
Prompt A
Disp "X2=?"
Prompt B
Disp "Y1=?"
Prompt C
Disp "Y2=?"
Prompt D
(A-B)^2 -->E
(C-D0^2 -->F
E+F -->G
Squareroot Sign G -->H
(A+B)/2 -->I
(C+D)/2 -->J
C-D -->K
A-B -->L
K/L -->M
Disp "DISTANCE="
Disp "Squareroot Sign (X)
Disp U
Pause
Disp "MIDPOINT="
Disp "X="
Disp I
Disp "Y="
Disp J
Pause
"SLOPE="
Disp M->Frac
END

Ok, Yes this is long but it shows all 3 in one prgogram and it gives u options incase it doesnt come out a whole number such as 2 root 5

mm

hey i made some programs which u might need give me a reply and i could load em um to the site

I'm hoping its what I'm looking for

I made a couple programs on the 83+SE. The series of programs are called "mathcheat.zip" in the archive. Hit it up, it's really useful for basic/"advanced" math classes, Geometry, Algebra, and Algebra II. Sooner or later, I'll make one for Calculus as that's what I'll be taking in school next.

HEY can you email them to me?MY email is jackpiser@hotmail.com

send me copies of the programs you made plz. I would really appreciat them kind sir. thank you for your generosity :-)

can you send them to me in a attached email file plz kind sure. i would really appreciate them. :-) also can you email me the text source code for the programs to im currently taking computer sci 1 and i could use that to even more help to figure out this basic programming stuff! :-) my email address is fisher724@hotmail.com

Can you email me the program at
bboy623@gmail.com

hey can you send that to Mexicanthief666@Aim.com

Thanks

I have a program on my calculator that works for midpoint distance and quadratic formula with imaginary numbers.i can send it to just gimme ur email address

HEy can yoyu seed them to me ? thanks email jackpiser@hotmail.com

can you send me them and the quadratic formula please , need quadratic by tuesday night

can you send them to me in a attached email file plz kind sure. i would really appreciate them. :-) also can you email me the text source code for the programs to im currently taking computer sci 1 and i could use that to even more help to figure out this basic programming stuff! :-) my email address is fisher724@hotmail.com

can't you just write a program like that?

exactly!

I really need a midpoint, distance and any new basic programing for a TI-83 plus. I am new at learning how to program my TI. please e-mail me with programs
lewis121@cox.net

can I get the quadratic formula please?
chica.loco@gmail.com
thanks!

easy. (L) = list

Prompt A,B,C
Fix 5
-2C/(B+{-1,1}sqrt(B^2+4ACi^2->l (L)Q
(L)Q(1)->K
(L)Q(2)->R
Disp K>Frac,R>Frac
Float

and tada. 71 bytes i think, and it shows imaginary solutions too.

My email is pjenks20@yahoo.com
please send those programs to me.
Thankyou

i have a program called XYhelper. i will post it.

I have made a functional quadratic formula program that finds real and imaginary roots (although it requires a small amount of thinking). The script goes as fallows:

REMINDER: Use the negative (-) sign when needed. Don't always use subtraction sign. Also all i's represent the value i not the letter. The value i is the 2nd function of the (.) key. In the script SQROOT means the square root function which is the 2nd function of the x^2 key.

:Disp "A"
:Input A
:Disp "B"
:Input B
:Disp "C"
:Input C
:(B^2+(-4*A*C))->F
:If F<0
:Then
:Disp "A + OR - SQROOT(B)i"
:Disp "OVER C"
:Disp -B,abs(f),(2*A)
:Else
:Disp "A + OR - SQROOT(B)"
:Disp "OVER C"
:Disp -B,F,(2*A)
:Disp "SIMPLIFY?"
:Disp "YES=1 NO=2"
:Prompt P
:If P=1
:Then
:(-B+SQROOT(F))/(2*A)->D
:(-B-SQROOT(F))/(2*A)->E
:Disp D,E
:Else
:End

Questions, comments, or problems email bmcdon07@yahoo.com

will you E-mail me all the formulas that you know, and just a quadratic formula not including imaginary numbers plaese.my email is kerfoot36@aol.com

Thank you

Is this program for an TI-83, because when I tried to do the A+ or -SQROOT(B) it said Error:Syntax?

I need to know how to put in an equals sign and a greater than sign if anyone can help

2nd-Math-1
Equals sign

2nd-Math-3
Greater than sign

thanks

in the 12th line it says abs(f) does that mean the letter f or is their something special to it?

That looks like a typing error. abs(F)

abs(A) means the absolute value
get it by:
[2nd] + [0] + [Enter]

If you press Mode and choose a+bi instead of real, then it will automatically display the imaginary roots also.

I just recently made a quadratic equation solver and it was my first attempt at programming anything but the code is a little shorter than this one and it still appears to work. The program displays both roots in complex numbers

:a+bi
:Prompt A,B,C
:Disp (-B +sqrt(B^2-4AC)/2A
:Disp (-B -sqrt(B^2-4AC)/2A

Actually, I think you should have
:Disp (-B + Sqrt(B^2-4AC))/(2A
:Disp (-B - Sqrt(B^2-4AC))/(2A

or else you will be adding B to the sqrt of B^2 - 4AC, which will be divided by 2 and multiplied by A.

Very common errors for quadratic formula programs.

I just uploaded a program to the archives for the 84+ that solves with imaginary numbers and also displays anwers as a simplified fraction.That might be helpful.

there is a much, much simpler way of handling this.

(L) = list

Prompt A,B,C
Fix 5
-2C/(B+{-1,1}sqrt(B^2+4ACi^2-> (L)Q
(L)Q(1)->K
(L)Q(2)->R
Disp K>Frac,R>Frac
Float

this gives imaginary solutions too.

My midpoint program is a little more friendly, but performs essentially the same functions as those listed above:
:Prompt W,X,Y,Z
:((W+X)/2)->A
:((Y+Z)/2)->B
:Disp "X IS",A
:Disp "Y IS",B

...and that's it.

you might want to use output instead of disp if you want it to be user friendly-it looks better if everything's lined up on the left.

What's the button for -> on the ti-83?

the [STO ->] button above [ON] (you didn't know that?)

Be nice everybody. Not everyone's a TIGC junkie. I would like to take the opportunity to say that if any you hardcore B.A.S.I.C want to make some easy $40-$120, make a algebra solver that does everything from slope to solving systems of quadratic inequalities, put it in a group, and see if it's under 8,000 RAM... It took me 'bout 4 months, but it seriously paid off!!!

Hey, could you name everything you had in your program? We'll see if i can create a program with less memory, eh?

I made a program called slope15 that is the ultimate xy plane line/point analyzer. It first asks you to input a line in one of three forms: two points, slope/point form, or standard form. It then gives lots of info about the line, I.E. slope midpoint, length, distance from intercepts, intercept location, etc.. Then you can chose from a set of functions. You can make a new line and compare it to the first (parallel, perpindicular, bisectors, etc.). You can input a point and it will tell you it's location in relation to the first line. You can find X(Y) or Y(X). Many other things can be done with combinations of the functions. I don't currently have a link cable but I will post it when I do.

These two programs together will give you exactly what you are asking for. The second one, "DISMID" calls on the first one, "DISTANCE", and releys on the fact that it leaves the cooridnates in the calculator's memory as A, B, C, and D. Make sure to name the first program "DISTANCE" in you calculator or it will not work.

Enjoy.

DISTANCE

Disp "POINT 1 X"
Input A
Disp "POINT 1 Y"
Input B
Disp "POINT 2 X"
Input C
Disp "POINT 2 Y"
Input D

Disp "DISTANCE IS:"
�((A+C)^2+(B+D)^2)üE
Disp E

DISMID

prgmDISTANCE
Disp "MIDPOINT X IS:"
(A+C)/2üF:Disp F:Disp "MIDPOINT Y IS:"
(B+D)/2üG
Disp G
Disp "MIDPOINT X IS:"
(A+C)/2üF:Disp F:Disp "MIDPOINT Y IS:"
(B+D)/2üG
Disp G

You are in luck! I have just made a Prgm recently that calculates the midpoint of point A(X1,Y1) and point B(X2,Y2),their midpoint, and most difficult: the location of point B(X2,Y2) given point A's location and the Midpoint. I should have it on my gaming clan's url shortly, as soon as I manage to debug the program. For now, I can give you the essentials:

The distance is the number of units between two points, as you know.
To find the distance, it is best you have a calculator;
BECAUSE MY COMPUTER DOESNT HAVE THE NEEDED CHARACTERS, I WILL USE WORDS!
vAv vBv
d=the square root of((X1-Y1)^2+(X2-Y2)^2)

If you wish, you can make the program yourself by doing something like:
:ClrHome
:Input "X1=",S
:Input "Y1=",D
:Input "X2=",F
:Input "Y2=",G
:[Enter the formula given above]
:Ans

The midpoint finder is on my calculator, which I left in my locker... Check my site soon and often!

I have a program already created for the TI-86 that computes midpoint, distance, as well as other useful algebra stuff (you can find it if you click on the url in this post).

I am just pointing out that just about about everything mentioned here has already been posted on the Archives for at least one calculator.

Personally, I use this on my 89. Two separate functions, quite easy to use and/or adapt for other calcs.

Midpoint:
m(x,y,z,t)
Func
({x,y}+{z,t})/2
EndFunc

Distance:
d(x,y,z,t)
Func
?((z-x)^2+(t-y)^2)
EndFunc

I like a simple approach.

For midpoint you could do the following

Input "X1",A
Input "X2",B
Input "Y1",C
Input "Y2",D
ClrHome
Output(3,7,((B+A)/2))
Output(6,7,((C+D)/2))

For Distance you could do

Here's a way to get slope, y-intercept, midpoint, and distance at the same time. It is kind of lengthy, but works great with a great interface (unless the numbers are huge).

:ClrHome
:Input "X1:",A
:Input "Y1:",B
:Input "X2:",C
:Input "Y2:",D
:Disp " "," ","
:(V-X)^2+(W-Y)^2->A
:If V=X
:Then
:Output(3,7,"None
:Output(4,7,"None
:1->N
:Goto N
:End
:(W-Y)/(V-X)->B
:Y-B*X->C
:Output(4,7,C
:Lbl N
:Output(1,1,"X1=
:Output(1,4,V
:Output(1,9,"Y1=
:Output(1,12,W
:Output(2,1,"X2=
:Output(2,4,X
:Output(2,9,"Y2=
:Output(2,12,Y
:Output(3,1,"Slope:
:If N/=1
:Output(3,7,B
:Output(4,1,"y-int:
:Output(5,1,"Midpt:X=
:Output(5,9,(X+V)/2
:Output(5,12,"Y=
:Output(6,1,"Dist:
:If int(&#8730;(A))=&#8730;(A
:Then
:Output(6,6,&#8730;(A
:Else
:Output(6,6,"&#8730;(
:Output(6,7,A
:Output(7,6,&#8730;(A
:End

&#8730; is the square root sign
-> is the store function
^2 is the squared function
I know this is long, but it gives you all you need to know. If you have any improvements or additions, please let me know.

Just download "Point Power". Don't bother looking at those scripts when its already been done.

hey bud do you want a program or just some information on how to write one because i have a really good one that i like alot if you'd like to check it out.

Here is a distance program:

:ClrHome
:Output(2,1,"DISTANCE BETWEEN A,B and D,C"
:Pause
:ClrHome
:Prompt A,B,C,D
:((C-A)^2 + (D-B)^2)^(1/2)->M
:Output(5,1,"DISTANCE:"
:Disp M

This is a program for distance and midpoint:

:ClrHome
:Output(2,1,"DISTANCE BETWEEN A,B and D,C AND MIDPOINT"
:Pause
:ClrHome
:Prompt A,B,C,D
:((C-A)^2 + (D-B)^2)^(1/2)->M
:Output(5,1,"DISTANCE:"
:Disp M
:(A+C)/2->X
:(B+D)/2->Y
:Pause
:ClrHome
:Disp "MIDPOINT:"
:Disp "X IS:",X
:Disp "Y IS:",Y

well , was thinkin about numerical analysis and signal processing. I be glad to supply all the necessary mathematical theorms and formulars. Please let me know we can do this together ... it will be cool if this idea can be a reality .Other EE and Math classes can be later . There are other programs on line but they are partially constructed, according to user or programer discreation. what you think ? hit me back

I love numerical methods, and would be more than willing to help. I am experienced with the TI-86, 89, and MS Excell . Let me know what you need.

Help : I am trying to enter formula in the PRGM the simple one are working prorprely but the difficul one doesn't work i must make mistake in the formula. can you help me an example on formula is
van= (R-C)/(1+k)-C

Can someone show the correct formula(r?) for solving systems of quadratic inequalities please? I wrote one before that only worked for about 20% of the equations I fed it. I've been prgming for 2 years in BASIC now, so I know I didn't have any syntactical errors in it. I have no clue why it wouldn't work at all at times. The graphing and table parts came out, but with the wrong equations totally... I know this screams twisted code but I've had my dad and brother pick out the code and except for the formula part they couldn't pick out anything wrong with it.
Oh, and please don't tell me to Google it, that's what I used to find the formula before and besides I think that math forums run by certain unnamed parties are massively unreliable.

i know a guy that might be able to help u. he programs all sorts of stuff like games and so on.

his email is

can anyone help me find a really good flash Math program? Thanks!

TI calculators are really good, but they need more memory, color screens, all 3D graphing for every calculator, cooler outside looks, and most \of all, a lot more good flash programs.

can anyone help me find ti flash programs?

can anyone help me find ti flash programs?

can anyone help me find ti flash programs? I need them!

I would make them if your that desperate.
I think the ti website has tools for it somwhere

What calculator?

WRITE THEM IN B.A.S.I.C. If you don't know how, browse the archives, find a nice, big, BASIC prgm and deassemble the code.

often times the functions you are looking for (solve for x if =0, converting ft -> km) are in the default settings in APPS or MATH
otherwise, MAKE IT YOUR SELF

i created various FOIL problems for precalculus classes, so i kinda got the hang of programming, the only problem i really have is that i can't seem to get a Synthetic Division program to work, i spent four hours, trying to figure out how to get it, so i tried looking it up, and i can't seem to find it

good news for you
i just wrote a synthetic division program last week that works perfectly. It finds roots and does specific divisions. send me your email at speakerofthegames@gmail.com and i will send you the program.

I also wrote, or set out to write, a Synthetic Division program, but it ended up as a Zero Finder for functions. If that is what you want to use it for, it is uploaded, check it out

Hi, I'm studying Trigonometry in my geometry class, and I was wondering if there was a program you can code to solve matrices when finding the coordinates of points rotated by theta degrees around the origin.
Example:
[cos(theta) -sin(theta)] [0 1 5]
[sin(theta) cos(theta)] [0 4 2]
Only as two matrices, one being 2x2 and the other 2x6

I figure you would need to prompt for theta, and the x and y coordinates of the points in the second matrix, but I'm not sure what to do from there....
Help is very much appreciated!

Sorry, I made a typo... I meant to say that one matrix is 2x2 and the other is 2x3-- not 2x6

Hello all, I have a TI-83+ and need some help with a program I am making.

I have a program that draws a circle with circledraw(0,0,1).

I want to be able to calculate calculate the points on the circle when the angle is 30*, 45*, 60*, 90*, 120*, 135*, 150*, 180*, etc..

The catch is that I need the points to be in simplest radical form (not floats). Any idea on how I would go about doing this?

I know that I use sine and cosine to calculate the points. for example:

coordinates for 60*

ClrHome
Degree
Input "Enter angle: ", I //Enter 60 here
cos(I) -> X
sin(I) -> Y
Output(3,1,"(")
Output(3,2,X)
Output(3,5,",")
Output(3,6,Y)
Output(3,9,")")
Stop
Radian
End

...but I don't know how to put them in simplest radical form.

Home or drawing screen can be used to display the points, I have no preference. Thanks!

I need help!
Can someone create a program for these, and possibly list them as an menu to chose from?
1.FoG
2.Gof
3.GoG
4.FoF
End.

Then on the same program
F+G
F-G
F*G
F/G

End

SUPER PLEASEE
I don't need them to cheat, I just need them so I can check my work and know I put the right answer.. so I can get an "A"

i want a program that can factorize an algebraic equation
"matt thats not what you need i have one ( that i built) you what need is a computer program that can translate basic ti too basic casio and back"

typood that isnt obvious hes a secret agent

Try this one
