Answer:

The description of the set is A = \{s\in \mathbb{C}|\|s\| = 2\}.

Step-by-step explanation:

From Complex Analysis, we remember that complex numbers are numbers whose form is:

s = a+i\, b, a,b \in \mathbb{R} (1)

Where i = \sqrt{-1}.

In addition, the distance from the origin is defined by the following Pythagorean identity:

\|s\| = \sqrt{a^{2}+b^{2}} (2)

The following condition must be satisfied:

\|s\| = 2

Then, the set of all complex numbers that are at a distance of 2 units from the origin is described below:

A = \{s\in \mathbb{C}|\|s\| = 2\} (3)
