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

(i) the line segment parametrized by z(t) = 2it, t∈{0,1}

(ii) the semicircle parametrized by z(t) = i + e^it, t∈{-pi/2, pi/2}

2. Relevant equations

3. The attempt at a solution

I know we have to sub the parameterization in for z, but now that theres a line and semicircle im confused! Didnt have a great prof for this subject, so im hopin some other people could help me out
