## RS Aggarwal Solutions Class 10 Maths Chapter 8 – Trigonometric Identities

The chapter Trigonometric Identities explains how to establish a relationship between other trigonometric ratios and inverse trigonometric identities.

Trigonometry is the study of relationships between angles, lengths, and heights of triangles. It includes ratios, function, identities, formulas to solve problems based on it, especially for right-angled triangles.

Applications of trigonometry are also found in engineering, astronomy, Physics, and architectural design. This chapter is very important as it comprises many topics like Linear Algebra, Calculus, and Statistics. This article on NCERT RS Aggarwal Solutions Class 10 Maths Chapter 8 Trigonometric Identities will give you an in-detailed idea about everything that will be necessary for you in the board exams.

## RS Aggarwal Solutions Class 10 Maths Chapter 8 Exercises – Trigonometric Identities

In Mathematics, trigonometry is one of the most important and prominent topics to learn. Trigonometry is basically the study of triangles. But in this article of NCERT RS Aggarwal Solutions Class 10 Maths Chapter 8 Trigonometric Identities, we will try to reduce the fear of trigonometry so that you will be able to scale up your marks and concepts.

By considering a right-angled triangle, trigonometry identities class 10 lists could be figured out. The trigonometric identities or equations are formed using trigonometry ratios for all the angles. Using trigonometry identities, we can express each trigonometric ratios in terms of other trigonometric ratios, and if any of the trigonometry ratios value is known to us, then we can find the values of other trigonometric ratios. We can also solve trigonometric identities class 10 questions, using these identities as well.

#### Trigonometric Identities for Class 10

In class 10th, there are basically three trigonometric identities, which we learn in the trigonometry chapter. They are:

- Cos
^{2}θ + Sin^{2 }θ = 1 - 1 + Tan
^{2 }θ = Sec^{2 }θ - 1 + Cot
^{2 }θ = Cosec^{2 }θ

## CBSE Class 10 Maths Notes Chapter 8 Trigonometry

- The position of a point P in the Cartesian plane with respect to co-ordinate axes is represented by the ordered pair (x, y).
- Trigonometry is the science of relationships between the sides and angles of a right-angled triangle.
- Trigonometric Ratios: Ratios of sides of right triangle are called trigonometric ratios.

Consider triangle ABC right-angled at B. These ratios are always defined with respect to acute angle ‘A’ or angle ‘C. - If one of the trigonometric ratios of an acute angle is known, the remaining trigonometric ratios of an angle can be easily determined.
- How to identify sides: Identify the angle with respect to which the t-ratios have to be calculated. Sides are always labeled with respect to the ‘θ’ being considered.

Let us look at both cases:

In a right triangle ABC, right-angled at B. Once we have identified the sides, we can define six t-Ratios with respect to the sides.
