Visualizing Sine and Cosine on a Unit Circle: Accurate or Not?

[mathzeroh]

Is this an accurate way of displaying sine and cosine on a unit circle?

Well, it doesn't really contain much information, and would probably not make sense to anyone who doesn't already know that the cosine is the x coordinate of points along the unit circle and the sine is the y coordinate.

Nice, I remember seeing that on the blackboard in my class a few years ago.

i think that's a much better representation.
