The polar form of a complex number z = a + b i is z = r ( cos θ + i sin θ) , where r = | z | = a 2 + b 2 , a = r cos θ and b = r sin θ , and θ = tan − 1 ( b a) for a > 0 and θ = tan − 1 ( b a) + π or θ = tan − 1 ( b a) + 180 ° for a < 0. Web polar form emphasizes the graphical attributes of complex numbers: Finding the absolute value of a complex number. Polar form of complex numbers plotting complex numbers in the complex plane.
