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

anonymous · Answer

residues are the best way to go about this problem

anonymous · Answer

well sure.. but im wondering about the contour

anonymous · Answer

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
