If A, B, and C are angled and a, b, and c are the sides of a triangle, then: The other three functions cosecant, secant, and cotangent are the reciprocals of sine, cosine, and tangent respectively. The basic functions of Trigonometry are sine, cosine, and tangent. This triangle is of great importance because if anyone tries to find the direct distance and angle, then that can be easily found using this. Here, in the figure, a right-angled triangle is shown having hypotenuse (the longest side), base (adjacent side), height (opposite side), and angle Ө. Trigonometry is used for finding the angles or the sides of the right-angled triangle. It plays the most vital role in almost all fields, whether it’s aviation, physics, criminology, military, marine biology, development of sound waves, satellite navigation, medical imaging etc.
It deals with the sides and angles of the right-angled triangle. Trigonometry is the most important concept in Mathematics.
According to Victor Katz in “A History of Mathematics (3 rd edition)”, Trigonometry was developed primarily from the needs of Greek and Indian Astronomers. This concept of Trigonometry was given by Greek Mathematician Hipparchus. It is the 16 th century Latin derivative.
The word Trigonometry is derived from the Greek word ‘Trigonon’ which means ‘triangle’ and ‘metron’ which refers to the term ‘measure’.
