Trigonometry is a branch of mathematics used to solve various numbers of problems using different formulae. The usage of trigonometry in real life is humungous. Some of the major places where trigonometry can be beneficial are: calculating the distance between the moon and earth and measuring the distance between two objects placed far from one another with missing inputs.\u00a0<\/span><\/p>\n

In this article, the students of CBSE Class 12<\/a> and JEE Main<\/a> aspirants will be able to understand the different trigonometric formulae and identities while learning about their related concepts.<\/span><\/p>\n

What is Trigonometry?<\/h3>\n

<\/a><\/p>\n

Trigonometry is a branch of Mathematics capable of dealing with a set of relations of the angles and sides of triangles. They also include their relevant functions at different angles. Trigonometry<\/a> in JEE Main includes solving problems using different trigonometric formulae.<\/span><\/p>\n

These problems include trigonometric ratios such as sin, sec, cos, cosec, tan and cot functions. Apart from that, they also consist of product identities, Pythagorean identities, etc.\u00a0<\/span><\/p>\n

Additionally, other formulae, including ratio signs in different quadrants, containing co-function identities, which are nothing but shifting angles, half-angle identities, double angle identities, sum and difference identities, etc., are explained in brief.<\/span><\/p>\n

List of Trigonometric formulae<\/h3>\n

It is common to consider only right-angled triangles when it comes to the formulae. There are three sides in right-angled triangles as Adjacent side (base), the Opposite side (Perpendicular), and the hypotenuse (longest side).<\/span><\/p>\n

The side present opposite the angle of the triangle is called the opposite side of the triangle. On the other hand, the hypotenuse is considered the longest side of the triangle and is often seen opposite the triangle’s right angle.\u00a0<\/span><\/p>\n
