The Law of Cosines (also called the Cosine Rule) is very useful for solving triangles: It works for any triangle: a, b and c are sides.
The cosine is similar, except that the adjacent side is used instead of the opposite side. Furthermore, sine and cosine are mutually orthogonal. The sine (abbreviated  sin ) and cosine ( cos ) are the two most prominent trigonometric functions.All other trig functions can be expressed in terms of them. In fact, the sine and cosine functions are closely related and can be expressed in terms of each other.Definition 1 is the simplest and most intuitive definition of the sine and cosine function. The sine definition basically says that, on a right triangle, the following measurements are related:n fact, the sine and cosine functions are closely related and can be expressed in terms of each other.
