radsimp.zip1k15-06-25File is not ratedRadical Simplifyer
Simplifies square roots.
quadrat80.zip1k08-02-28File is not ratedQuadrat 80 v1.0 Quadratic formula solver
A very simple, easy to use quadratic formula solver for your TI 80! Just type it in the program editor and solve quadratic equations with ease! Approximately 150 Bytes!
golden89.zip22k06-04-19File is not ratedGolden Ratio (All TI's & DOS)
Each program finds the Golden Ratio and stores it to B. The DOS version simply tells you the Golden Ratio and shows the same math as the TI versions (but MUCH faster).
pythag89.zip27k06-04-15File rated 3.87Optimal Pythagorean Solvers
This solves for any variable in the Pythagorean Theorem. It's made in TI-Basic for all TI's; QBasic for IBM PC DOS; and z80 asm on the 83+ & 86. All TI-Basic version have been optimized extensively and tested for errors.
tandraw.zip2k05-12-17File is not ratedTag Drawer
This program will draw the tangent or the normal of any function you define, in any domain range or image range you also define, at the point you want. More features included.
tanmker.txt3k05-12-17File is not ratedTan Maker
Draws tangents on a parabola for certain X coordinates.
quad80.zip1k04-05-12File is not ratedQuadrametric Graphing
polar80.zip1k04-05-11File is not ratedPolar Graphing
powroot.zip6k03-06-19File is not ratedAny Root Finder (Guess-n-Check Method)
This is simple to use. You input the number, the root you want to find (2 for square, 3 for cube, etc), and how many decimal places. It'll only show the TI's limit in decimal places, but is pretty cool nonetheless. Quickly made for every TI.
pieuler89.zip2k03-05-18File is not ratedPi: Euler's Method
This package of programs for all TI's quickly converges to pi using one of Euler's methods.
systems.zip1k02-11-01File is not ratedSystems v1.0
This program solves for x and y if you have two equations in the form AX+BY=C. Since the TI-80 lacks matrices, this program can really come in handy. Enjoy!
polygon80.zip1k02-10-24File is not ratedPolygon v1.0
This program finds the area of a regular polygon when given the number of sides, and the length of one side. It gives the same answer, no matter if you're in degree or radian mode. Wow!
badmath80.zip1k02-08-02File is not ratedBadMath v1.0
When you run this program, it looks like you are on the home screen, but you aren't. The PRGM button, MODE, and the 5 keys on the top row (Y= to GRAPH) are disabled. If you try and do any math problems, the answer the program returns will be off by up to 10%. It's a pretty simple program, but it's fun to mess with people who ask to borrow your calculator. To quit, press ON. Enjoy!
primetest.zip1k02-05-11File is not ratedPrime Test
Works for all numbers less than 1 EE 10. That's because that's this poor calc's limit. I'm getting an 83+ soon (I hope). It works on the highest prime I could find (999999989) in about half-a-minute. It also displays the first factor it finds.
