Vasco,Here are my takes on Chapter 4, Exercises 20 and 21. Twenty is much like your answer and derivative in parts. Twenty-one is an ongoing adventure.

By following the link above I see that you are starting to work through chapter 5, and reading through your solution to the suggested exercise on page 219 I discovered a typo:
In the third equation from the bottom there is an $r$ missing in the last term and an extra closing bracket at the end. The last term should be $-Rr\partial_r(\psi)$.
This typo is carried through to the second equation from the bottom which should be $\partial_{\theta}(R)=-rR\partial_r(\psi)$.

Just noticed the (more or less) same typo on line 4 in your statement of the exercise. 6/12/2015
