that works.. its still a little unclear. You will have to do some algebra to simplify then use identities to simplify again.

I am not certain how far you are expected to go... but Proffs usually want to see the work and simplification and present it to them in the simplest form.

Simplifying as much as possible before diff'ing usually improves the outcome of the differentiation.

any monkey can plug the problem into a computer and write the complicated, inelegant answer.
