## anonymous 4 years ago The point (0.58544, -0.81072) lies on the unit circle. If a terminal arm is drawn through this point, what is the cosine ratio of the angle?

1. anonymous

cosine is the x coordinate component of the given point, 0.58544

Can you please draw a diagram by any chance? I understand it, but at the same time, I don't - like with cos, tan, and sin

Hint: All points on the unit circle have coordinates: $$(cos(\theta), sin(\theta))$$
