How do I find the equation of a derivative using a TI-84?

    I want to know how to do this so after I find the equation by hand, I can check to see if I am correct.

    Thanks for the post! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post?

    I don't know about the TI-84, but Wolfram Alpha will do it and is easy to use.

    Ti 84 does not do symbolic execution. I guess you can go to the plotter and input
    Math->differentiate(f(a),a,0,x) as y1(x)
    and what you think the derivative is as y2(x)
    and see if they line up, or test certain values numerically.

    But yah, the best option is to use a CAS, such as Mathematica/WolframAlpha or the TI 89
