Which of the following explains why Cosine 60 degrees = sine 30 degrees using the unit circle?
The answer is: The side opposite a 30° angle is the same as the side adjacent to a 60° angle in a right triangle. On a unit circle, the (sin) distance of a 30° angle is the same as the x (cos) distance of a 60° angle.
But I would really appreciate someone to explain this to me, thank you!
