Chain Rule with Two Inner Functions

This applet facilitates practice on derivatives of funnctions requiring chain rule with two inner functions like . Such functions are composite of three functions.
First find derivative yourself. Then compare with the solution provided by the applet. If you do not understand how to apply chain rule to composition of three functions you are advised to observe solutions of derivative of a few functions provided by this applet. Sometimes simplification provided by the applet can be weird looking. For more on chain rule check my online book "Flipped Classroom Calculus of Single Variable"
