Best ResponseYou've already chosen the best response.0At 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)

Best ResponseYou've already chosen the best response.2If you know the Residue Theorem you can cut your work from computing three line integrals to one.

Best ResponseYou've already chosen the best response.2Your line integral on the first line is z = 1 +i y dz = i dy \[ \int_0^{1} \frac{i}{1+i y} \, dy=\frac{1}{4} (\ln(4)i \pi ) \]

Best ResponseYou've already chosen the best response.0hmm then will i continue with 1/4(ln4.... or i always use the i/1+iy

Best ResponseYou've already chosen the best response.2for the second integral z= x I dz = dx \[\int_1^{1} \frac{1}{xi} \, dx=\frac{1}{2} (i \pi ) \]

Best ResponseYou've already chosen the best response.2How much is y on the second line? 1 How much is x on the seconfd line? x from 1 to 1 z= x i
