Complex Number to Rectangular Form Calculator

Convert Polar to Rectangular Form

The distance from the origin to the complex number in the complex plane.
The angle measured counter-clockwise from the positive real axis.

Unlock the power of complex number conversions! Our user-friendly calculator effortlessly transforms complex numbers from their polar form (magnitude and angle) into the familiar rectangular form (x + yi). Ideal for students and engineers, this tool simplifies complex number arithmetic and visualization. Input 'r' and 'θ' to get 'x' and 'y' instantly!

Formula:

A complex number in polar form is typically represented as r(cos θ + i sin θ), where r is the magnitude (modulus) and θ is the angle (argument).

To convert this to rectangular form (x + yi), we use the following formulas:

  • x = r cos θ
  • y = r sin θ

Where r is the magnitude and θ is the angle in radians (our calculator handles degrees internally).
