This is Tom from the Worldwide Center of Mathematics walking you through important and useful features of your TI-84 graphing calculator.

This TI-84 plus graphing calculator series is meant to be an instructional walkthrough that covers some of the most often used functions on a TI-84. This particular video covers calculus and shows the viewer how to calculate numerical derivatives and definite integrals. The software used in this video is TI-Smartview.

You are a heaven sent! I am studying for a math teaching exam and this is going to save my life! Thank you!!

One warning you should include: The calculator will estimate a derivative even if one doesn't exist. For example, on the function y = |x| at x=0 the derivative doesn't exist because of the sharp turn (left and right limits of the difference quotient aren't equal). However, the calculator will tell you the derivative is zero there. This could lead into an interesting discussion of numerical analysis.

I bought a TI-84 Plus C Silver Edition because of this video. I like how it tells you what to fill in unlike the TI-83 I already own where it was more like a function. However when I received my calculator today I hit [math] and choose 8: nderive and it is a function just like TI-83. Is there a setting or an update or what to get it to look like this one?
