[TIB] Re: solver
On the 86 I believe it searches arbitrary values for the variable and
evaluates them on both sides of the equation. Then it subtracts one
from the other. When this value changes sign, it attempts to find
exactly where it changed signs, or where it was equal to zero. And when
the right side of the equation minus the left side equals zero, the
equation is true. It then displays the value of x (or whatever
variable) it used to get the two sides equal.
On the TI-89, I don't have a clue how it works.
