I don't know how to show this:

Can anyone help? Thanks.
Obviously you are just differnetiating first using the rule for differentiating arcsin but then once I evaluate it all I do not get the required solution.

I'm reading it from a past paper and it does have the '2' in front of the strangely. Either way, i'm not sure on a couple of parts of your method.
Firstly,
In the 1st line of the differentiation, the 3rd term, I am unsure of why there is an in the square root, should this not be over 16?
Secondly,
I do not understand how you went from the first line to
is obvious but the other part is not so clear.
