How to evaluate a complex integral using Cauchy integral formula

WebNov 29, 2016 · Then the integral formula is. f ( x) = 1 2 π i ∫ c − i ∞ c + i ∞ F ( s) e − s x d s. Which is (when F is proper rational function) computed by a semicircle to the left of the line Re s = c. Again using the other semicircle doesn't work in that case as the integral over that semicircle does not go to zero. Share.
