Who is This Topic Relevant For?
Imagine a circle with a radius of 1, centered at the origin of a coordinate plane. This is the unit circle. When a point on the unit circle is connected to the origin, it forms a right-angled triangle with one corner at the origin. The sine and cosine of an angle are defined as the ratios of the lengths of the sides of this triangle. The sine of an angle is the ratio of the length of the side opposite the angle to the hypotenuse (the side opposite the right angle), while the cosine of an angle is the ratio of the length of the side adjacent to the angle to the hypotenuse.
