Polar to Cartesian form Exponential form Principal argument If is the principal argument of a complex number then Cartesian form (Real/Imaginary form) Cartesian to Polar form NB. You may need to add or subtract to in order that gives in the correct quadrant Polar form (Modulus/Argument form) Re Complex numbers: Forms Im Im Re Eulers formula Main page
