Here's a message that I posted about a week ago. I found a small bug
in the program pts.85p, and I've fixed it now.
Attached are some programs that I've written for the TI-85 for Math Team,
and my classes (I'm a sophmore).
Side note - Our Math Team is going to
state!! You'll find them helpful for Geometry, Algebra II /
Trig, and a little for Calculus. You will need to get a viewer (if you
don't already have one) because I decided that it would be crazy to try and post
them as text files with all those funky symbls. You can get TI's graph
link software for free at
www.ti.com.
Base.85p
The best / fastest / smallest base number converter you will find. I wrote
it so that it converts directly from one base to another, none of that
converting to base 10 crap. Because it uses lists, it can handle very
large bases.
Fact.85p
This spits out factors
of a number. I found a bunch of things that sped it up a
lot.
PFact.85p
This lists all prime factors
of a number
Pts.85p
This takes two points,
determines the distance between them (AS A REDUCED RADICAL), the midpoint,
slope, and y-intercept.
Rsimp.85p
Ever had to
reduce a large radical like Root of 720? This program will do it, and
return 12 Root 5 as the answer.
Synth.85p
Use
this program to do synthetic
division.
Tri.85p
This calculates area of a
triangle based either on coordinates of the vertices, or the length of the
sides.
Enjoy.
