I guess i should first ask, is it proper form here to start new threads or edit my old ones... either way, i'll post in this new one for now.

Trying to work out y' of the square root of x-1 / x+1 (all terms inside the root, didnt know how to indicate that in text)

I assume that I make it (x-1 / x+1)^1/2 but i get into a very tangly equation when I use the quotient rule. Is this the right way to start here?
