"Equation solver" on the ti 89 and 84 question

[shinny]

Ah crap, I didn't mean exactly as I've typed it there as in with the quotation marks ahah

oooo right lol...awesome thanks!

the numerical solve function is rather "incomplete". this is the case with the equation solver on 84, and the nSolve function [as well as solve function on 89 when it doesn't have an exact solution]

what it does is it searches from left to right, and return the first matching approximate value then disregard everything else. that's why on the 89 when you ask it to solve a rather complex thing, it always says "warning: more solutions may exist" in the bottom left.
