2. Relevant equations

∫h(r)*dr = ∫h[r(u)]*r'(u)du

3. The attempt at a solution

I was able to figure out plugging in (t^2+3) at every x and sin(1/2πt) at every y. I then set up the dot product of the substituted equation and r'(u)du (2t + 1/2πcos(1/2πt)). The problem is, the integral ends up being much to complex to work by hand since I'm not allowed to use a calculator for this problem. So I was wondering if there was an easier way to work this problem out?
