Exponential and polar forms of a complex number

Allowed: constants, operators and i. For the product, use* Ex: a*b and not ab

This tool converts a complex number from the algebraic format (a + b.i) to its exponential and polar forms.

Graphic representation

z is a complex number represented by the point M on the plane of complex numbers as follows,


Polar form

The polar form of z is written,

`z = r *( cos(\varphi) + i * sin(\varphi))`

r = |z| is the modulus of z.
`\varphi` is the argument of z.

Exponential form

The exponential z format is written,
`z = r * e^(i*\varphi)`
