TI-89 "How To..." Index

BHS -> Mr. Stanbrough -> AP Calculus -> this page

The following pages are designed to help you use your TI-89 calculator effectively and efficiently in AP Calculus. It is assumed that you are familiar with the operation of a typical graphing calculator, so only features unique to the TI-89 and AP Calculus are discussed.

On the TI-89, how do I...

absolute values
- enter absolute values into the TI-89?
- interpret absolute value statements?
calculate the average value of a function?
handle composition of functions?
test for concavity of functions?
calculate derivatives?
convert radians to degrees and vice-versa?
use f(x) notation?
avoid doing something really dumb...
- the graph of y = |ln x| on the TI-89?

figure out the home screen?
tell whether a function is increasing or decreasing?
implicit functions:
- do implicit differentiation?
