Given:
There is a unit circle given in the question
Required:
We need to find that for what value, sin function is -1
Explanation:
As we know that x cooedinate represents the cos function and y coordinat represents the sin function
So here
[tex]\begin{gathered} sin\theta=-1 \\ \theta=sin^{-1}1 \\ \theta=\frac{3\pi}{2} \end{gathered}[/tex]
Final answer:
[tex]\theta=\frac{3\pi}{2}[/tex]
