If I recall grad school correctly, the contour integral of f around z_infinity is not simply the negative of the contour integral of f around the origin. I never understood why not. I don't think I could pose the question to Mathematica properly, anytime soon. So I thought I'd bring it to this list. Would someone formulate these two contour integrals as Mathematica expressions, and attempt to draw an equality between the two? I'd be curious to see how Mathematica takes it. If this is nonsense, just leave it in wonderland. Thanks, Vince Virgilio
