You need to use the chain rule here: so the answer is (4 x cos^4 (pix  13)) x (sin( pix  13)) x pi.

Where did you get the 4 from?

Oh sorry replace the 4 in front with a 5! so the first part should be ( 5cos^4(pix 13))(sin(pix  13))(pi)

So the whole answer is what I posted above  that's not just the first part

So the (sin) shouldn't be raised to the 5?

nope! because the first part of the chain rule is finding the derivative of (x^5), and the second is finding the derivative of (cos x), and the third part of the chain rule is finding the derivative of (pix  13).

so you already took care of the raising to the 5 in the first part of the answer, where we have that termed raised to the 4.
