Can the TI-83 Plus do calculus?
In this chapter, you learned about the (limited) tools your TI-83 Plus or TI-84 Plus includes to help you with calculus. We worked on finding the slope of a function at any point by calculating its numerical derivative at that point.
How do I take the derivative?
To take the derivative of a function by using the definition, substitute x plus delta x into the function for each instance of x. Then, substitute the new function into the limit, and evaluate the limit to find the derivative.
How do I find derivatives?
Basically, we can compute the derivative of f(x) using the limit definition of derivatives with the following steps:
- Find f(x + h).
- Plug f(x + h), f(x), and h into the limit definition of a derivative.
- Simplify the difference quotient.
- Take the limit, as h approaches 0, of the simplified difference quotient.
How do you use derivatives on the TI-83/84?
Derivatives on TI-83/84. The TI-83/84 is helpful in checking your work, but first you must always find the derivative by calculus methods. (See your calculus text.) The TI-83/84 sometimes finds a derivative where none exists (for instance, the derivative of | x | at 0), and if you haven’t found the derivative yourself you may be fooled.

How do you find the derivative on a calculator?
The calculator displays the derivative at the bottom of the screen. You can get the derivative at other points, if you need to. Press [2nd F4makesCALC] [6] again, enter the new xvalue, and press [ENTER]. What’s New?
