This applet gives students a chance to get feedback on taking the derivative of a long list of functions.
The included functions do not use product or quotient rule.
They also do not use the chain rule other than with a linear function.
The applet has a difficulty slider that allows the user to decide the kinds of functions that are allowed.
1) Algebraic functions only
2) Exponential and log functions are also allowed. (This is the standard level for business calculus.)
3) Trig functions are are allowed. (This is the standard level for regular calculus on the first pass.)
4) Inverse Trig functions are allowed.
5) Hyperbolic trig functions allowed.
To check an answer, the student should hit the show derivative button.

Students should try to get 10 problems in a row correct.
