Hi guys!
I'm currently writing a piece of work involving bessel functions J, K and I of order 0 and 1.
I need to find the values of K'(x)/K(x), I'(x)/I(x) ad J'(x)/J(x) around x=0. My supervisor suggested looking into methods like pinching and squeezing but really have no idea where to start.
Squeezing sounds a good idea but don't really know where to start, I just wondered if anyone could offer me any advice?
