complex integral: integral of (2z-4)*e^(mz)/(z^2-4z+3) from 2-i*(infinity) to 2+i*(infinity) for every m different from 0. well i know there are 2 poles at 1 and 3 and i think i should use jordan's lemma and then residues

OpenStudy (anonymous):

residues are the best way to go about this problem

OpenStudy (anonymous):

well sure.. but im wondering about the contour

OpenStudy (anonymous):

ill give more detailed attempt for a solution.. for a positive m i think about closing a semi circle which encloses the pole at 1 and for a negative m closing a semi circle which encloses the pole at 3
