Ok so for the first integral and the line segment... int from 0 to 1 {(2it bar) ^ 2 +1} (2i) dz i worked this out and the answer i got was -2/3 i? is this right? and so for the semicircle the integral wil be int from -pi/2 to pi/2 {(-1 + e^it bar) ^2 + 1 (e^it) } ?

Homework Statement Hey people got a question here about complex integration, not really sure how to do it so hope someone out there could help me! Evaluate the complex integrals ∫ c { (zbar)^2 +1 } dz...and...∫ c { zcos(z^2) - ie^2z } where c is the contour joining 0 to 2i along...
