Question

Complete the table with the cosine, sine, and coordinates of 0, π/2,π , and 3π/2.

Look at screenshot for table.

Answer 1

Please consider the complete table.    

We have been given a table. We are asked to complete the given table.

We know that point $(x,y)$ represents $(\text{cos},\text{sin})$ on unit circle.

We know that value of y is 0 on x-axis, so value of sine on x-axis would be 0.

We also know that value of x is 0 on y-axis, so value of cosine on y-axis would be 0.

The value of $\text{cos}(0)=1$ and $\text{sin}(0)=0$.

$\text{cos}(\right\frac{\pi}{2}\left)=0$ and $\text{sin}(\right\frac{\pi}{2}\left)=1$.

$\text{cos}(\pi)=-1$ and $\text{sin}(\pi)=0$.

$\text{cos}(\right\frac{3\pi}{2}\left)=0$ and $\text{sin}(\right\frac{3\pi}{2}\left)=-1$.

Therefore, the complete table will be as attached in the file.
