let g denote the elliptic arc parametrized by z(t) = 2cost + 3isint, for t between 0 and pi/2 (inclusive).
Evaluate the integral of f(z) = z[sin(pi*z^2) - cos(pi*z^2)] over g.
If g is determined by the function z mapping from [a,b] to C and f maps from g to C, then the integral of f over g is defined as the integral (from a to b) of f of z(t) times z'(t).
(sorry for writing the equations out in words, I don't have any formatting software)
The Attempt at a Solution
I started by finding z'(t) = -2sint + 3icost and attempting to find f(z(t)), but I got a really complicated function and at that point I figured I must be going about it the wrong way.
I tried to find an identity that would allow me to simplifiy f(z) but I couldn't find anything.
At this point I really have no idea how to proceed.
