In the polar form of a complex number z = r(cos θ + i sin θ), what term is used for the distance 'r'?
Show answer
Modulus (or Magnitude)
The modulus 'r' represents the distance of the complex number from the origin in the complex plane. It is calculated as the square root of the sum of the squares of the real and imaginary parts.
