Homework Statement
The problem is to differentiate the function.
y=cos4(x2 + ex)
Homework Equations
cos(x)'= -sin(x), (xn)'=n*xn-1, (ex)'=ex*x'
The Attempt at a Solution
Thought it would be the chain rule. Here's what I came up with:
y'=4cos3(-sin(x2 + ex)(2x + ex)
Is this right? If not, any suggestions on what I did wrong?
