On this page you can visually see the step by step thought process that you should be using when imagining the unit circle in your head. You can write in an angle, and observe the steps and get the sine and cosine value of that angle at the end.
For the specific important values that are required for the school, you will see it in that form.(i.e.√3/2)
For the angle(θ): °
Cos ° = None
Sin ° = None
Coordinates: (None, None)
