Solve for the angle $theta$ if the point $(0, -1)$ is on the unit circle
Answer 1
Benjamin Clark
On the unit circle, each point corresponds to an angle measured counterclockwise from the positive $x$-axis:
1. The point $(0, -1)$ lies at the bottom of the unit circle.
2. This corresponds to an angle of:
$$ \theta = \frac{3\pi}{2} \, \text{radians or } 270^\circ $$
