ConceptPolar Form / 极坐标形式
Polar Representation
A mathematical method of representing a complex number by its modulus and argument, in the form z = re^{iθ}. It makes multiplication, division, and exponentiation of complex numbers intuitive, and is one of the core representations for complex number operations.
