1. Suppose C is simple closed curve in the plane given by the parametric equation and recall that the outward unit normal vector n to C is given by y(t r'(t) If g is a scalar field on C with gradient Vg, we define the normal derivative Dng by and we define the Laplacian, V2g, of g by For this problem, assume D and C satisfy the hypotheses of Green's Theorem and the appropriate partial derivatives of f...

Step 6 So ultimately the crux of the matter is to find antiderivatives for these two functions The former is one you should already have an idea for (from your experience with calculating derivatives of inverse trigonometric functions). The latter is analogous, but can be dealt with by a useful trick you may have seen in precalculus: Find real numbers A and B to make this true, then use it to give an antiderivative for Notes on polynomial division will...
