NCERT Maths Class 11

The sophisticated numerical modulus provides a complex numerical distance from the base of the argand plane.

The complex number modulus is the point distance to the argand plane, representing the complex number z from its base.

Let P be the point that shows the complex number z = x + iy.

All complex numbers with the same module lie in the middle root and radius r = | z |.
