The answers to all of math hell by William Blake This new Version 1.20 of MATHHELL adds the new program PHYSICS for kinematics as well as the original programs CMPINT(Compound Interest Solver), LAWS(Now Simplified), LGRAPH(Linear Equation Solver), and QUAD(now combines QUAD and QGRAPH) As always just run ANYMATH and it will link you to the programs that you need. This works for TI 83 and 83+ but on the 83+ make sure you don't have any of the programs it links (if you haven't figured it out:CMPINT, LAWS, LGRAPH, QUAD, and PHYSICS) archived or they won't work. Also included in this package is VIRUS (No it won't destroy your caculator) it just clears you real variables to clear up RAM space and runs GarbageCollect Question? Comments? Problems? Suggestions?
