where the region R' in polar coordinates is R' = { < < , f( ) < r < g( )}.
Double integrals in polar coordinates can be entered in the calculator, making
sure that the Jacobian |J| = r is included in the integrand. The following is an
example of a double integral calculated in polar coordinates, shown step-by-
step:
