WebDec 8, 2024 · The only example problems up to this point involved computing Jacobians to make a change of variables in multiple integrals. A basic example of such a transformation would be how the volume element in cartesian coordinates ##dxdydz## transforms to ##r^2 sin\theta dr d\theta d\phi## where ##r^2 sin\theta## is the determinant of the Jacobian … WebThe length in the r and z directions is dr and dz, respectively. The length in the theta direction is r*d(theta), and this yields the result for the volume. This result can also derived via the Jacobian. For some problems one must integrate with respect to r or theta first. For example, if g_1(theta,z)<=r<=g_2(theta,z), then freeze baked chicken
