How do I calculate cos, sine, etc. without a calculator?
Yes, I remember learning about it in school. But I don't remember how to use it to calculate sine and cosine.
Essentially, the unit circle is a circle with a radius of 1. To find the x-coordinate (cosine) and y-coordinate (sine) of a point on the unit circle, you can use the angle between the point and the x-axis. The cosine of the angle is the x-coordinate, and the sine of the angle is the y-coordinate.
