Cos-Derivative
y= (cos^3 x) (cos 3x) I got -3 sin(3x) cos^3x - 3 sin(x) cos (3x) cos^2 (x) using the product rule Is this right? Thanks.
Derivatives
I have taken that into consideration; thank you!
Derivatives
I got 12 sin (3x-1)^2 cos (3x-1)^2 * (3x-1) as my final answer. Is this in the correct simplified form ?
Derivatives
I'm not sure if this is correct. Can someone clarify thanks.
Derivatives
what is derivative of sin^2 (3x-1)^2 ? dy/dx (sin^2 (x))= 2 sin x cos x dy/dx (3x-1)^2= 6(3x-1) chain rule? = 2 sin ((3x-1)^2) cos ((3x-1)^2) * 6(3x-1) Please help. Thank you

This is correct!

W= 5L So the side lengths are 5L and L. by definition of a right triangle (5L)^2 + (L)^2= ? 25L^2 + L^2= 26L^2 This matches choice C.
