Question

What are the coordinates of the terminal point corresponding to 0=-120?

Answer 1

Using the unit circle, the coordinates of the terminal point corresponding to $\theta = 120^\circ$ is: (-0.5, 0.866).

What is the unit circle?

For an angle $\theta$ the unit circle is a circle with radius 1 containing the following set of points: $(\cos{\theta}, \sin{\theta})$.

In this problem, the angle is of $\theta = 120^\circ$, hence:

• $\cos{\theta} = \cos{120^\circ} = -0.5$.

• $\sin{\theta} = \sin{120^\circ} = 0.866$.

Hence the terminal point is:

(-0.5, 0.866).
