At first I though this wasn't going to be so hard, but then I read the subinstructions >_< @amistre64 , @TuringTest , any insight on this one guys? PS: You did post ALL the contextual information for this one this time right @SkykhanFalcon ? ;) (/me remembers your last superchallenging differentials question)

If you know the Residue Theorem you can cut your work from computing three line integrals to one.

Your line integral on the first line is z = 1 +i y dz = i dy \[ \int_0^{1} \frac{i}{1+i y} \, dy=\frac{1}{4} (\ln(4)i \pi ) \]

for the second integral z= x I dz = dx \[\int_1^{1} \frac{1}{xi} \, dx=\frac{1}{2} (i \pi ) \]

how can i understand the integral part for ex. why the second one become 1/xi

How much is y on the second line? 1 How much is x on the seconfd line? x from 1 to 1 z= x i
