Solutions to homework # 5 II.31. (a) Consider the rectangular contour CR consisting of the intervals IR :=[R, R], + SR :=[R, R + 2 i/b], JR :=[R + 2 i/b, R + 2 i/b], SR :=[R + 2 i/b, R]. First note th
Solutions to homework # 4 II.27. (a) Res f (i) = lim(z i)f (z ) = lim(z i)
z i z i
z2 i2 z2 = lim = . (z i)(z + i) z i z + i 2i
(b) Since e1/z 1 = e1 e1/z , we get e1/z 1 = e1 (1 + 1 1 + + ). 1!z 2!z
