Hi, I'm not sure how to find the derivatives of the following: $\displaystyle y = x^x, y = x^{\cos x}$ I think you use a variant of the chain rule but not sure how. Thanks

Take the $\displaystyle \ln $ of both sides, $\displaystyle \ln y = \ln x^x = x \ln x$ then implicit differentiation.
Ahh simple stuff, thanks!
