# Chain Rule With Two Inner Functions (Composition of Three Fu

Topic:
Functions
This applet can be used to find derivative of a composite function generated with one inner function (composition of two functions). Enter Inner function in x middle function in t, and outer function in u. You are advised to solve the problem using pen and paper before comparing with the solution given by this applet. Please note that the simplification produced in the applet may differ from yours and may not look neat sometimes. Use this applet for practice on chain rule with one inner function
You should have studied differentiating constant times, sum/difference, product, and quotient rules of differentiation and feel fairly comfortable with them. For more on chain rule check my online book "Flipped Classroom Calculus of Single Variable" https://versal.com/learn/vh45au/
