Let the surface (S) be the part of the elliptic paraboloid z = x2 + 4y2lying below the plane z = 1. We define the orientation of (S) by taking the unit normal vector ⃗n pointing in the positive direction of z− axis (the inner normal vector to the surface). Further, let C denotes the curve of the intersection of the paraboloid z = x2 + 4y2 and the plane z = 1 oriented counterclockwise when viewed from positive z−...
