IB Mathematics SL – Calculus, Derivatives, Differentiation Chain Rule

We know that the derivative of composite functions is given by the following formula



The chain rule states that the derivative of a function of a function (composite function) equals derivative of the outer function times derivative of the inner function.

So about your question we view as a composite function , where .


Using the Chain rule we obtain





Hope these help!! :) :)
