I'm having trouble figuring out how to find the derivative of x^{cosx}. I know the answer is x^{cosx }(-sinx lnx + (cosx)/x) but i have no idea how to get there.

I also encouraged student to study the following and be able to tell me by way of logarithmic differentiation why it is true.
Suppose that each of is a differential function, then
