Answer 1

Given:

There is a unit circle given in the question

Required:

We need to find that for what value, sin function is -1

Step-by-step explanation:

As we know that x cooedinate represents the cos function and y coordinat represents the sin function

So here

`\begin{gathered} sin\theta=-1 \\ \theta=sin^(-1)1 \\ \theta=(3\pi)/(2) \end{gathered}`

Final answer:

`\theta=(3\pi)/(2)`
