The Polar Complex Number Calculator is a powerful tool used in mathematics to convert complex numbers from Cartesian coordinates (real and imaginary parts) to polar coordinates (magnitude and argument). It simplifies the process of representing complex numbers in a polar form, providing insight into their geometric interpretation.

Formula of Polar Complex Number Calculator

The conversion from Cartesian to polar coordinates is based on the following formulas:

r = sqrt(x^2 + y^2) θ = atan2(y, x)

Where:

  • r is the magnitude (or modulus) of the complex number,
  • θ is the argument (or phase) of the complex number,
  • x is the real part of the complex number, and
  • y is the imaginary part of the complex number.

These formulas allow us to express a complex number in terms of its distance from the origin (r) and the angle it makes with the positive real axis (θ).

Suppose we have a complex number with Cartesian coordinates x = 3 and y = 4. Using the calculator, we find:

r = sqrt(3^2 + 4^2) = sqrt(9 + 16) = sqrt(25) = 5 θ = atan2(4, 3) ≈ 0.93 radians

Therefore, the polar representation of the complex number is r = 5 and θ ≈ 0.93 radians.
