I don't know how to begin solving the second part of the following question:
i. Given that show that can be written in the form:
and state the value of k.
(This part is fine and I got k = 3)
ii. Hence evaluate
I do not know how to begin this part. This question is from a differentiation section of the textbook I'm using and so far I have learned only the chain and product rules and do not know how to integrate this so I assume that I am expected to solve this from the first part of the question. If someone could point me in the right direction I would appreciate it.
