What is Meant by Cosine Function?

In Mathematics, trigonometry is a branch that deals with sides and angles of the right-angle triangle. The six important trigonometric functions are obtained based on the sides of the right triangle. The three most common trigonometric functions are sine, cosine, and tangent. The reciprocal of these functions are cosecant, secant and cotangent. The cosine function is a function which is the ratio of the adjacent side to the hypotenuse of the right triangle. Thus, the cosine angle can be calculated using the formula, 

Cos θ = Adjacent Side / Hypotenuse
