Homework Help: Integral proof help

  1. May 9, 2010 #1
    I am soooo poor at this kind of proof problem...:cry:
    Please help me out with this!

    Show that

    Integral_C y dx + x dy depends only on the endpoints of the arbitrary curve C.

    (Hint: find a potential function f of the vector field <y, x> and use that to integrate
    along a parametrization r(t) = <x(t), y(t)> of C with endpoints at t = a and t = b.)

    I also attached a jpg file!

    Thank you,

    Re: Proof

    have you tried the hint? finding a scalar potential should be reasonably staightforward
