## Importance of ML Aggarwal Class 10 Maths Chapter 18 Trigonometric Identities

This chapter is all about how trigonometric ratios are formulated. The values of the angles of a triangle are related to the values of its sides. We can find the pattern by using these trigonometric formulas.

This chapter explains all the ratios and the relationship between them. This relationship between sine, cosine, cosec, sec, tan, and cotangent ratios gives rise to trigonometric identities. These identities are universal and are true for trigonometric angles ranging between 0 and 90 degrees.

The derivation of these identities will be explained in this chapter. Students will find out how the trigonometric ratios are related through these equations. These angles are determined based on a right-angled triangle and the ratios of its sides.

It includes the base, perpendicular, and hypotenuse of a right-angled triangle. The changes in the two angles other than the right angle will be determined using these identities. The chapter will describe how these identities are applicable for these two angles whose sum is 90 degrees. Referring to the ICSE Class 10 Maths Chapter Trigonometry Solutions will make it even clearer.

The chapter will then proceed to the utilisation of these identities to formulate exercise questions. These exercises will help students to determine their understanding of the Trigonometric Identities Class 10 ICSE and preparation level. Hence, following the solutions becomes mandatory for preparing this chapter.

## Benefits of ICSE Maths Solutions for Class 10 Chapter 18 ML Aggarwal

• As mentioned earlier, this chapter is very important for the development of a conceptual foundation related to identities. Hence, the solutions will be very helpful to find out how to apply them to solve the questions.

## FAQs on ML Aggarwal Solutions for Class 10 Maths Chapter 18 Trigonometric Identities - PDF

1. What is the Sine of an angle?

The Sine of an angle is the ratio of the perpendicular and the hypotenuse of a right-angled triangle.

2. What is the cosine of an angle?

The ratio between the base and the hypotenuse of a right-angled triangle is called the cosine of that angle.

3. What is the tangent ratio of an angle?

The ratio between the perpendicular and the base of a right-angled triangle is called the tangent of that angle.

4. What is a right-angled triangle?

A triangle whose one angle is equal to 90 degrees is called a right-angled triangle.

5. What is the hypotenuse of a right-angled triangle?

The longest side of a right-angled triangle lying opposite to the right angle is called the hypotenuse.
