Here is the Relation and function class 12 formulas What is Relations A relation R from a non-empty set A to a non-empty set B is a subset of the Cartesian product A × B. It “maps” elements of one set to another set. The subset is derived by describing a relationship between the first […]

Trigonometry is an essential branch of mathematics and is included in the CBSE board curriculum. The cosine function is one of the six trigonometric functions and is often used to describe periodic phenomena. In this article, we will provide an overview of cos 2x, its properties, and its applications. Cos 2x Formula The formula of

In this post ,we will see how we can write all the Trigonometric ratios of angle A in the terms of sin A. Here we would be focusing on acute angle A only Value of sin A in terms of cosec A $sin A = \frac {1}{cosec A}$ Value of Cos A in terms of

In this post ,we will see how we can write all the Trigonometric ratios of angle A in the terms of sin A. Here we would be focusing on acute angle A only Value of cos A in terms of tan A From Trigonometric Identity $\sec ^2 A =1 + \tan ^2 A$or$\frac {1}{\cos ^2

In this post ,we will see how we can write all the Trigonometric ratios of angle A in the terms of cos A. Here we would be focusing on acute angle A only Value of sin A in terms of sin A From Trigonometric Identity $\sin ^2 A + \cos ^2 A= 1$or$\sin ^2 A

For any triangle , we have following formula involving trigonometric ratios. Trigonometry formula for triangle Formula 1 $\frac {sin A}{a} = \frac {sin B}{c} = \frac {sin C}{c}$ Formula 2 $cos A = \frac {b^2 + c^2 -a^2}{2bc}$ $cos B = \frac {a^2 + c^2 -b^2}{2ac}$ $cos C = \frac {a^2 + b^2 -c^2}{2ab}$ Formula
