Given F = iy - jx (this is my first post; not sure how you do vector notation here but I'm showing vectors in bold - hope that works). The problem is to show that this is a non-conservative force by integrating from the origin to (1,1) (ie, the path is y=x), and then do it again from the origin to (0,1) and from there to (1,1). I just don't get how to set up the integrals - can someone help? I understand the concept behind the line integrals, but hit a brickwall trying to apply it. Thanks.
