How do you add two complex vectors?

Published in Complex Vector Math 2 mins read

To add two complex vectors, you add their corresponding real and imaginary components separately.

Here's a breakdown:

Let's say you have two complex vectors:

  • Vector A: a + bi
  • Vector B: c + di

Where:

  • a and c are the real components.
  • b and d are the imaginary components.
  • 'i' represents the imaginary unit (√-1).

The resultant vector (Vector C) from adding Vector A and Vector B is calculated as follows:

Vector C = Vector A + Vector B = (a + c) + (b + d)i

In essence:

  • The real component of the resultant vector (Vector C) is the sum of the real components of Vector A and Vector B (a + c).
  • The imaginary component of the resultant vector (Vector C) is the sum of the imaginary components of Vector A and Vector B (b + d).

Example:

Let Vector A = 3 + 2i and Vector B = 1 - 4i. Then:

Vector C = (3 + 1) + (2 + (-4))i = 4 - 2i

In summary, you add the real parts together and the imaginary parts together separately to obtain the real and imaginary parts of the resultant vector.
