USING the TI-83
Finding roots, verifying that a point is on a curve,
locating a common point for two curves, and finding

the derivative at a certain point are just a few of

the powers hinden in a graphing calculator. In the

example above, we are looking for the zeros

of a function. After inserting the function into

the "y=" screen, we use "2nd - calc - zero"

buttons. We will need to enter a LEFT and

RIGHT boundary and then hit "ENTER"
