![]() When dealing with more complex functions, this way of thinking helps to keep yourself on track and not get lost in what functions are taken with respect to what variables, etc. The second layer is the function inside the parentheses. Keep in mind that everything we’ve learned about power rule. With practice, you will see that applying the chain rule is easiest if you "peel away the onion." The first layer is everything inside the parentheses, cubed. Let’s look at how chain rule works in combination with trigonometric functions.That is, if f is a function and g is a function, then the chain rule expresses the derivative of the composite function f g in terms of the derivatives of f and g. ![]() Step 3: Differentiate inner function and multiply by the answer from. Practice your math skills and learn step by step.
