Let f = u + iv be a contiunous function and o(t) = x(t) + iy(t) be a piecewise smooth curve... Show that Re{ integral (f(z) dz } = integral (udx - vdy) How do I show this?

Yes, that I want Im trying to show. I really don't know how to approach this problem, so I havn't done anything. I was hoping to see how this one is done so I can do a similiar proof (the imaginary part) by myself... Please help
