I am having trouble with the following question, any help would be blinding.
Find the value of ther derivative of:
(z - i)/(z + i) at i.
I tried to use the fact that f'(z0) = lim z->z0 [f(z) - f(z0)]/z - z0. I also tried using the fact that z = x + iy and rationalising the denominator, but had no joy either way.
Probably just being stupid!
