Learn How to Calculate Modulus of Complex Number - Tutorial

Definition:

Modulus of a complex number is the distance of the complex number from the origin in a complex plane and is equal to the square root of the sum of the squares of the real and imaginary parts of the number.

Example:

The modulus of complex number z = 7 + 5i

Given,

a=7, b=5 i.e. z = 7 + 5i

To find,

Find Modulus of complex number. |z|,

Solution

Step 1:

Substitute the given value of a, b in the formula |z|,
