Polar & rectangular forms of complex numbers

Polar to Cartesian Calculator: [Polar Coordinates Calculator]

SOLVED:Use a CAS to change the Cartesian integrals into an equivalent polar integral and evaluate the polar integral. Perform the following steps in each exercise. a. Plot the Cartesian region of integration in the x y -plane. b. Change each boundary curve of the Cartesian region in part (a) to its polar representation by solving its Cartesian equation for r and θc. Using the results in part (b), plot the polar region of integration in the r θ-plane. d. Change the integrand from Cartesian to pol
