The image asks to complete the table for values of $\cos(x)$ for specific values of $x$ in radians. Let's go through the values of $x$ given and compute $\cos(x)$.

1. $x = 0$: $\cos(0) = 1$ This value is already provided.

2. $x = \frac{\pi}{2}$: $\cos\left(\frac{\pi}{2}\right) = 0$ The empty box should be filled with 0.

3. $x = \pi$: $\cos(\pi) = -1$ This value is already provided.

4. $x = \frac{3\pi}{2}$: $\cos\left(\frac{3\pi}{2}\right) = 0$ The empty box should be filled with 0.

5. $x = 2\pi$: $\cos(2\pi) = 1$ The empty box should be filled with 1.

Completed Table:

• $\cos(0) = 1$
• $\cos\left(\frac{\pi}{2}\right) = 0$
• $\cos(\pi) = -1$
• $\cos\left(\frac{3\pi}{2}\right) = 0$
• $\cos(2\pi) = 1$
