I=∫_2^∞ (1/(x(x-2)^.5)) dx
using the calculus of residues. be sure to choose an appropriate contour and to explain what happens on each part of that contour.
transform to a complex integral
I= ∮ (1/(z(z-2)^.5)) dz
The Attempt at a Solution
i don't even know where to really begin. i keep ending up dividing by zero
