Step 1:
I'll solve this step by step following the specified LaTeX formatting guidelines:

Step 2:
: Understand the Trigonometric Equation

The equation $$\cos(x) = 1$$ means we are looking for all angle values where the cosine function equals 1.

Step 3:
: Recall the Unit Circle Properties

In the unit circle, $$\cos(x)$$ equals 1 only at specific angle values.
These are points where the cosine function reaches its maximum value of 1.

Step 4:
: Identify the Angle Solutions

- And so on for all integer values of $$k
The cosine function equals 1 at the following angles: This means the solutions are:

Final Answer

The solutions are x = 2\pi k, where k \in \mathbb{Z} (k is any integer), which includes ..., - 4\pi, - 2\pi, 0, 2\pi, 4\pi, ...
