find derivs of f(x) = e^(sinx), f(x) = cosx/x^2, (cosx)^3,

[whytehaze]

Find the derivatives of the following functions:

a. f(x)=e^(sinx)
b. f(x)= (cos x/x^2)
c. (cos x)^3
d. x sin(x^2)

2. Let f(x)=(3x^4)-(4x^3)+(2)
a. Find all the critical points of f(x), Give both cordinates of each.
b. classify each critical point as a local maximum, local minimum, or neither one.
