If f(x)=sin(x4), find f′(x)
f′(x)=
Find f′(5)
f′(5)=
To solve this problem, you'll need to apply the chain rule. Remember, when differentiating a composite function like sin(x4), you'll need to differentiate the outer function (sine) and multiply it by the derivative of the inner function (x4). Pay attention to how you differentiate the power function inside.
