y = (cos(x))^2 + cos(x^2) //power rule for the cos(x). also you have to take the derivative of the inside of the cos(x) y' = 2*(cos(x))*(sin(x)) + d/dx(cos(x^2)) // now take the derivative of the second part of the sum. no power rule. just take derivative of the cos() and then the derivative of the inside. y' = 2*(cos(x))*(sin(x)) + (sin(x^2))*(2x) // so you can factor a 2 if you want.

Why would you have the first sin(x)?

Shouldn't it just be 1? I'm lost.
