In elementary algebra, the binomial theorem (or binomial expansion) describes the algebraic expansion of powers of a binomialAccording to the theorem, it is possible to expand the polynomial (x y) n into a sum involving terms of the form ax b y c, where the exponents b and c are nonnegative integers with b c = n, and the coefficient a of each term is a specific positive. Jan 06, 09 · Please help, I am trying to prove that dF1/dy = dF2/dx, in terms of the above vector field = F(x,y) = F1(x, y) i F2(x, y) j = (y / (x^2 y^2)) i (x / (x^2y^2)) j but then I get that (1/(x^2 y^2)) (2y^2/((x^2y^2)^2)) = (1/(x^2y^2)) (2x^2/((x^2y^2)^2)) if that makes sense, but then these are only equal if the negatives can be turned around, and if y^2 = x^2, but that means.
