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
