How do I get from the problem to the answer using the chain rule?
It would be much appreciated if someone indicated the steps for me, thank you!
1. You need the product rule:
, where the chain rule has also been used.
Then you substitute the above results into .
Some simplification of the resulting answer will be possible .....

2. You need the quotient rule:
.
Then you substitute the above results into .
Some simplification (requiring a little bit of algebra) of the resulting answer will be desirable .....
