MathWiz v2.1 released
Posted on 19 January 1999, 21:23 GMT

Fred Coughlin has released MathWiz v2.1 for the TI-83. This program is similar to Kirk Meyer's Cymbol program in that it features a grapical interface for selecting various external applets that perform mathematical functions. Changes over version 2.0 include various bug fixes, the ability to switch applets in mid-program, and the support of many more applets (200 in theory). The distributed archive includes the source code for three applets and instructions for making your own applets. If there is interest, a separate directory will be made on this site for these applets.

Re: MathWiz v2.1 released

This program sucks. I can make better programs.

Re: MathWiz v2.1 released

Ok, I think I found an error in the program.
The first thing that I did when I loaded the program was run the quadratic equation applet. Then I pushed mode to get back to teh applet screen, and decided that I wanted to quit. So, I pushed mode thinking that it was the quit key. Then I realized that clear was the quit key, but when I pressed it, nothing happened. In fact, NO buttons worked. I had to take a battery out to get my calcultor back. You might want to look into this.

Fred C.

Thanks, David. I fixed the bug, and sent a new version in to the site. (I forgot a little pop statement... which of course messes up the program)... Thanks for pointing it out, adn the corrected version should be up soon.

Re: MathWiz v2.1 released

I don't realy see the point of programs such as this. The calcs are all designed to be used for mathematics. If you just RTFM you'll find that the calcs can do most anything you need for your math classes. If the calc you own can't do what you need for your class then you should probably consider buying one that is a bit better. Also, by the way, if you need an expensive graphing calc for an algebra class, then you probably don't belong in that class.

Some people can't remember everything, or don't want to. That is why I think that this is a good program. But, it is an advantage in that, in basic at least (dont know about asm), you can program the equation in and get the answer in a fraction of the time that all of your classmates do. And, IT IS ALWAYS RIGHT!

Re: Re: Re: MathWiz v2.1 released

I'm not not knocking this prgm. I've never used it I am not able to use it (my lowest graphing calc is an 85). I'm just knocking math prgms in general. For an algebra class you realy don't need any calc at all. I was without a calc until 2/3 of the way through algebra 2. Then I got a TI-36x solar (scientific calc), and hardly ever used it except for once and a while in Math League. When I stared pre calc I decided it was about time for a graphing calc, I hardly used it all year except for programing. Now I am in AP calc and I still hardly need it, I could get by with my old 36x solar just as easily, I just wouldn't be able to spend my free class time programing. So I don't see how one could possibly NEED a math prgm, or even a graphing calc for that matter, in an algebra class. You don't have to memorize everything for an algebra test, all you have to do is pay attention to what the teacher says and shows you on the board, and do your homework once in a while (and notice I said once in a while, I barely ever do my math homework and I am still able to get A's and B's.) If you can't do these simplistic things to pass an algebra test maybe you should just go out now and buy your apren to prepare for your future of flipping burgers.

I'm sorry if I sound like your parents and/or teachers, but that's just my viewpoint.

Re: Re: Re: Re: MathWiz v2.1 released

Is it just me or did your message turn into a dialog about your accomplishments about halfway through the post? In any case, you can be very succesful with only a basic grasp of algebra(if any). Having difficulty with mathematics beyond the basics does not doom you to a life of flipping burgers.

Prove by induction that n(n^2 - 1)(3n + 2) is a multiple of 24 where n is any positive integer and A is an integer.
Find the value of the term independent of x in the binomial expansion of
(56(x^2) + 4/(3(x^4))^12.

Re: Re: Re: Re: Re: MathWiz v2.1 released

Yeah, now that I reread it, it does sort of look that way. However that was not my intent. I was just trying to explain my point of view. Kind of like, (well here are my experiences whith calcs and math classes, now maybe you can see where I'm coming from and why I don't think a math prgm is useful.)If that last sentence made no sense what so ever, I'm sorry, I have trouble sometimes finding words to fit my thoughts. I didn't mean that one would be doomed to flipping burgers if they have difficulty with math. I meant if they are too lazy to pay attention and do their homework once in a while then they might not get very far in life. I only have 1 minute of time left on the library computer, so I'll post later with the answers to your problems.

Re: Re: MathWiz v2.1 released
Calc as Crutch

How on earth would you get an answer faster if you need to run a basic program, or assembly for that matter. The calcs will do almost anything if you know what you are doing. Obviously that is not case. You give knowledgable programmers a bad name. Go bite your mother.

thank you and good evening.

Re: Re: Re: MathWiz v2.1 released

I don't quite understand what just exactly you mean by that. Can you make it a little more clear?

     21 January 1999, 20:24 GMT

Re: Re: Re: MathWiz v2.1 released

Example: matrix
It is a lot easier to punch in the numbers in a program and get the output than it is to do all of the equations out by hand. (especially the larger ones) I know that there is a matrix menu, but that take a while too!

     22 January 1999, 01:45 GMT

Re: Re: Re: Re: MathWiz v2.1 released

True it easier than by hand, but a prgm is limited in that it is only useful if you intend to the same type of problem over and over again. Whereas the matrix functions built into the calc are versatile, they alow you to do the same thing over and over, or many different thngs, and they're just as easy to learn and to use as a prgm. Also a prgm would take extra RAM and the matrix functions are already there and require nothing extra.

     22 January 1999, 16:55 GMT

Re: Re: Re: Re: Re: MathWiz v2.1 released

Yes, a program will take up some RAM, but only around one hundred and fifty. Whereas a simple three by three matrix (made using the "matrix" menu) will take up about ninty bytes. (Not that big a difference)

     23 January 1999, 01:41 GMT

Re: Re: Re: Re: Re: Re: MathWiz v2.1 released

On my 86 a 3 by 3 matrix takes up 98+(# of letters in name)bytes. 150? that's kind of a small prgm, even if it is in asm.

Re: Re: Re: MathWiz v2.1 released
What is your problem?

Sorry, O master programer. You must be the best programmer in the world, huh. Oh yeah, what is your problem. Must you use that language. (expression) I guess you don't see the point of this message board. *Hint- you are not supposed to use it for degrading people.

     22 January 1999, 03:57 GMT

Re: MathWiz v2.1 released

I know this is off the topic, but where could I go for applets for Cymbol for the 86?

Re: MathWiz v2.1

how many of you remember writing that program for solving quadratic equations in Algebra I,
I don't know about you but typing in the values of A, b, and c, and pressing enter were alot faster than pressing x^2 + 4x -20.

I think The applets are just fine,
and I'm sure some people will use them more than the regular TI-os,
but then the ti-os is good to,
On the 92 I see only two functions not built in,
custom log bases and custom roots,
beleive it or not I havan't found a way yet to express the 19 root of N except n^(1/19)

As for the not using a calculator in Algebra,
If you had a choice would you graph y = x^2 + 29x + 16 by hand or puch it in to your calculator,
Yes it is lazy but it is faster and more accurate,
But I could see while you'd rather do things bhy hand, You do get extremely fast at it,

Ti-os and Applets are about equal,

Re: Re: MathWiz v2.1

Instead of wasting my time writing a prgm I learned how to use the poly menu (I have an 86). I don't know about your class, but when I was in algebra, we usualy didn't graph second degree equations, except once or twice when we firt started learning about them. I am slower than molasis in January at math, I just think one might learn more than if they constantly rely on their calc.

     28 January 1999, 02:18 GMT

Re: Re: Re: MathWiz v2.1

I didn't say that the Poly menu wasn't good,
but still typing in a, b, and c, and pressing enter is still faster than using the poly menu,

Your right we didn't graph them to often,
but there was that one or two homework assignments that said you had to graph 16 or more of them,
that just took to long by hand,
but I am now in Pre-Calc as a sophomore and It is easy to do those,
but it is still faster by calc than by hand, (most of the time)

     28 January 1999, 22:15 GMT

Re: Re: Re: Re: MathWiz v2.1

True, there were those few asignments, but I don't think that justifies wasting space on a math prgm. I do like to graph on calc rather than by hand, but at least a few times by hand just for the experience of it, but just use the built in grapher rather than a prgm.

Re: Re: Re: Re: MathWiz v2.1

Also, I don't know if you bother to look at this any more since it's on the old news, but sorry I didn't reply for so long, I had a bad cold for about 4 days.
