What is Meant by Trigonometry?

In Maths, trigonometry is a branch that deals with the sides and the measure of the angle for the right angle triangle. The trigonometric function is also known as the circular function. Based on the angles and the sides, the trigonometric functions are classified into six important types. They are Sine, Cosine, Tangent, Cosecant, Secant, and Cotangent. The ratio to define these function are given below:

Sin Function  = Opposite Side/Hypotenuse

Cos Function = Adjacent/ Hypotenuse

Tan Function = Opposite Side / Adjacent Side

Cosec Function = Hypotenuse / Opposite Side

Sec Function = Hypotenuse / Adjacent Side

Cot Function = Adjacent Side / Opposite Side
