What's the circle in math called with values for radians?

[AgaBoogaBoo]

What's the name of the circle that let's you easily remember radian values based on degrees?

For example, cos 0 will tell you it has an x coordinate value of 1, so cos0 = 1, etc.

hmmm interesting... being in engineering i had to deal with a lot of trig stuff but i had NEVER seen that diagram until now

Thanks for the link... it'll save me from drawing it again for a handout this fall.

I would highly suggest learning that then. Its not something that should be skipped

I think that circle is call a calculator

The unit circle is something you should definitely learn and understand. It'll prove to be useful.

If you need a calculator for what that circle shows, it's means you're not good in math and should consider another field in lieu of engineering.
