How do you convert the Cartesian coordinates (3, - 3) to polar coordinates? Precalculus Polar Coordinates Converting Coordinates from Rectangular to Polar 1 Answer José Roberto Pereira Oct 19, 2015 #P=4.2426/_-45^(o)# Explanation: The module is: #m^2=3^2+3^2# #m^2=9+9# #m=sqrt(18)=4.2426# The angle is: #phi=tan^-1(-3/3)# #phi=-45^(o)# #P=4.2426/_-45^(o)# Answer link Related questions What are the polar coordinates of #(0, -2)#?
