Is addition and one when it is subtraction x^ {2}yxy^ {2}=43 x 2 y x y 2 = 4 3 Subtract 43Using the binomial coefficients, the above formula can be written as (x y)n = (n 0)xn (n 1)xn − 1y (n 2)xn − 2y2 (n k)xn − kyk (n n)yn where (n k) = n!Figure 1572 Double change of variable At this point we are twothirds done with the task we know the r θ limits of integration, and we can easily convert the function to the new variables √x2 y2 = √r2cos2θ r2sin2θ = r√cos2θ sin2θ = r The final, and most difficult, task is to figure out what replaces dxdy
