Answer 2

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(\pi)/(2)\left)=0` and
`\text{sin}(\right(\pi)/(2)\left)=1`.

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

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

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