Trigonometry Basics Part – 2 | Advanced Trigonometry | Trigonometry Easy Concept By Abhinay Sharma (Abhinay Maths)

Trigonometry is a branch of mathematics that studies relationships involving lengths and angles of triangles. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies.

The main functions in trigonometry are Sine, Cosine and Tangent. They are simply one side of a right-angled triangle divided by another. For any angle “θ”: (Sine, Cosine and Tangent are often abbreviated to sin, cos and tan.)

Trigonometry is defined as one of the branches of mathematics that deals with the relationships that involve lengths and also the angles of triangles. In a simple manner, we can say that Trigonometry is the study of triangles.

A simple proof of the very important and useful trigonometry Identity sin^2(x) + cos^2(x) = 1 is shown. Also the notation for squaring trigonometric functions is shown. Since the proof requires the use of the Pythagorean theorem, this identity is called the Pythagorean trigonometric identity.
