The image you've uploaded contains a trigonometric equation and a step-by-step process to solve it. I’ll walk you through the problem in more detail, but here’s a rough breakdown of what I see:

1. The equation starts with:
   \[
   \sqrt{2} \cdot \cos \left( 2\pi x - \frac{\pi}{3} \right) + 1 = 0
   \]
   
2. After rearranging the terms and simplifying, you seem to isolate the cosine term:
   \[
   \cos \left( 2\pi x - \frac{\pi}{3} \right) = -\frac{1}{\sqrt{2}}
   \]

3. This leads to solving for \( x \), involving the arccosine function:
   \[
   2\pi x - \frac{\pi}{3} = \pm \arccos \left( -\frac{1}{\sqrt{2}} \right) + 2\pi k
   \]
   
4. Solving further gives general solutions for \( x \), which likely results in:
   \[
   x = \frac{something}{2\pi} \ldots
   \]

Would you like me to write out all the steps and detailed explanations? 

Here are five related questions to deepen your understanding:
1. How do we solve trigonometric equations involving cosine or sine functions?
2. What is the role of the arccosine function in solving this equation?
3. How do we handle general solutions for periodic functions like cosine?
4. Why do we add \( 2\pi k \) when solving for angles in trigonometry?
5. How does the factor of \( \sqrt{2} \) affect the cosine function?

**Tip:** When solving trigonometric equations, always remember to consider the periodic nature of sine and cosine to capture all possible solutions.
