What is Trigonometry?

Trigonometry is considered one of the most significant branches of mathematics. The word trigonometry is formed by combining the words 'Trigonon' and 'Metron' which means triangle and measure respectively. Trigonometry is the study of the relation between the sides and angles of a right-angled triangle. It thus helps in finding the measure of unknown dimensions of a right-angled triangle using formulas and identities based on this relationship. There are three basic functions in trigonometry - sine, cosine, and tangent.

Real-Life Applications of Trigonometry

As we have already discovered, the applications of trigonometry are seen in different fields in real life. Let us look at all these fields briefly to understand the application of trigonometry better.
