Calc2.4

From Exampleproblems

Find the derivative of $f(x)\,$ with respect to $x\,$ : $f(x)=\sin^4 x\,$

This problem is a chain rule problem. Our outside function is a power function because $\sin x\,$ is raised to the fourth power. Our inside function is $\sin x\,$ .

$f'(x)=4\sin^3 (x)\cos (x)\,$
