Triangle Solver

More or less a beta version (its been tested, but not stress tested). Its coded for the TI-89. The ASCII/Text versions are posted as well in case someone has the urge to convert it for another calculator. Its been a while since I’ve done any TI BASIC coding so this was hammered out without too much thought in organizing the code.

Text version
TI ASCII Program version
TI-89 Program (right-click and save-as)

To use, just provide 3 parts of the triangle and the program will calculate the other 3 parts. If there’s 2 solutions available, it will produce the 2nd solution as well.

Trig Formulas Online

I finally got around to posting my collection of trig formulas (handy for pre-calc). You can find them here:

Just copy the text (with all the goofy characters) over to the TI GraphLink Program Editor and save it as a program (it won’t run so you’ll need to go to Program Edit on your calculator)

It looked as though Mozi was going to call it a season and nap. He did move to his basking site and hung out with his eyes half open. I figure by this weekend he’s going to shut down till the next time change…

Pre-Calc – The saga continues

In a once in a lifetime occurance, I managed to score a 90 out of 100 on my pre-calc test – part deux. I found out from the prof I had the highest score in that class, although not the highest score between her two classes (highest was a 94). Then add on the 10 bonus points for doing the review! I can’t get too comfy-cozy and slack off in this class. Just roughly 4 more weeks!
