Explanation of Solution
Given:
Concept used:
The absolute value or modulus of complex number is the distance between the origin
Formula to find the absolute value of any complex number:
To plot the graph:
Step 1. Determine the real and imaginary party of the complex number.
Step2. Move along the horizontal axis to show the real part of the number.
Step3. Move parallel to the vertical to show the imaginary part of the number.
Step4. Plot the point.
Calculation:
Consider the complex number
The above complex number can be written as
The plot complex number
The absolute value of
Hence the absolute value is
