Have you considered factoring out sec(x) from the numerator?
This might be more of a trig question, so if it is would someone kindly move it for me?
So I'm finding the second derivative of . My first derivative is .
My question is: can I simplify this fraction to make taking the second derivative less tedious? I'm capable of doing it without simplifying first, but I don't want to get a super long and ugly answer.
