Having trouble with this question, I need to calculate the line integral of 2xsin(y) dx + (x^2 * cos(y) - 3y^2) with the given parametrization r(t) = (t*cos(t), t^2*sin(t)) with 0 <= t <= 2pi

are you sure about the first line of the problem, something is messing?

The first line isn't in any way connected to the parametrization...maybe double check what you put down?

Or is it? :P Is x supposed to equal t*cos(t) and y supposed to equal t^2*sin(t)? (haven't done parametric equations yet, but I want to give it a shot).
