Answer 1

If you draw a circle wir radius 1 around the origin of a coordinate system, and you pick any point on that circle and draw a line to the origin, this line forms an angle with the x-axis.

The x-coordinate of your point is the cos of the angle, the y-coordinate is the sin of the angle. You find a picture of this under the term “unit circle”
