Answer 6

wow thats the stupidest way ive ever seen to find the derivative of x^2.

Answer 7

To find the derivative for this function, factor out the 1/3 because that is just a constant. Next, you're going to use chain rule for the trig functions inside the parenthesis. The derivative of the OUTSIDE multiplied by the derivative of the inside.

Think of the trig functions as: \[[\sin(x)]^3 //[\cos(x)]^3\]

that might help you.
