Converts rectangular to polar and displays r. Converts rectangular to polar and displays q. Example Convert polar coordinates (r, q)=(5, 30) into rectangular coordinates. Then convert rectangular coordinates (x, y) = (3, 4) into polar coordinates. Round the results to one decimal place. R³´P - q $ $ " " < 23
