## Important Definition for RS Aggarwal Chapter 8 Class 10 Maths Ex 8a Solutions

RS Aggarwal Solutions for Chapter 8 lets you know that:

- sin A = side opposite to angle A /Hypotenuse
- cos A = side adjacent to angle A/hypotenuse
- tan A = side opposite to angle A/ side adjacent to angle A

In RS Aggarwal Solutions for Chapter – ‘Trigonometric Identities’, you will get to understand that if one of the trigonometric ratios of an acute angle is given to you, then you can easily determine the remaining trigonometric ratios.

- cosec A = 1/sin A ; sec A = 1/cos A ; tan A = 1/cot A, tan A = sin A /cos A
