Let f(x) cos(arcsin(x)) a) First find the derivative by using Chain Rule f'(x) = b) Next, we will find the derivative in a different way. Rewrite f(x) without trigonometric functions (Hint: Set up a right triangle with a side x). When finished this step, f(x) can be written as: have you f(x) = Then find the derivative of this equivalent form of f. f'(x)
