Dxdy to rdrdtheta
WebHere we use the identity cos^2(theta)+sin^2(theta)=1. The above result is another way of deriving the result dA=rdrd(theta).. Now we compute compute the Jacobian for the change of variables from Cartesian coordinates to spherical coordinates.. Recall that WebThe factor dM = ˆdxdy = dxdy (since ˆ= 1) The limits on x integration are 0 and 3, and the limits on y integration are 0 and 2, so x = R 2 0 R 3 0 xdxdy R 2 0 3 0 dxdy = 9 6 = 3 2 y = R 2 0 R 3 0 ydxdy R 2 0 R 3 0 dxdy = 6 6 = 1 Not surprising, the center of mass is the centroid and is right in the middle of rectangle Patrick K.
