RD Sharma Solutions Class 10 Maths chapter 5

RD Sharma Solutions Class 10 Maths chapter 5: Chapter 5 of RD Sharma's Class 10 Maths, Trigonometric Ratios, introduces students to the fundamentals of trigonometry, specifically focusing on defining and calculating trigonometric ratios for acute angles. The chapter covers the six main trigonometric ratios: sine, cosine, tangent, cosecant, secant, and cotangent, derived from the sides of a right-angled triangle.

Through examples and problems, students learn to find these ratios for given angles and understand their significance in solving real-world problems involving heights, distances, and angles. The chapter lays the groundwork for further studies in trigonometry, preparing students for advanced applications in later classes.

RD Sharma Solutions Class 10 Maths chapter 5 Overview

Chapter 5 of RD Sharma’s Class 10 Maths, Trigonometric Ratios, introduces foundational concepts of trigonometry that are crucial for higher mathematics and various practical applications. This chapter covers the basic trigonometric ratios—sine, cosine, tangent, cosecant, secant, and cotangent—derived from right-angled triangles. Understanding these ratios is essential as they form the basis for solving problems involving angles and distances, widely applied in fields like physics, engineering, and architecture.

Mastery of trigonometric ratios not only enhances problem-solving skills but also prepares students for advanced topics like calculus and analytical geometry in later grades.

What are Trigonometric Ratios?

The sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec) are the six trigonometric ratios. The study of the sides and angles of a right-angled triangle is known as trigonometry in geometry. Trig ratios are therefore assessed in relation to sides and angles.
Trigonometric Ratios
Sin θ Opposite Side to θ/Hypotenuse
Cos θ Adjacent Side to θ/Hypotenuse
Tan θ Opposite Side/Adjacent Side & Sin θ/Cos θ
Cot θ Adjacent Side/Opposite Side & 1/tan θ
Sec θ Hypotenuse/Adjacent Side & 1/cos θ
Cosec θ Hypotenuse/Opposite Side & 1/sin θ
Note: The right triangle's base is on the adjacent side, while the perpendicular side is on the opposite side. For further in-depth information on any of these ratios or functions, see trigonometric functions.

RD Sharma Solutions Class 10 Maths Chapter 5 FAQs

What do you mean by trigonometric ratios?

Trigonometric Ratios are defined as the values of all the trigonometric functions based on the value of the ratio of sides in a right-angled triangle.

Which trigonometric ratio is defined?

Trigonometric ratios are the ratios of the length of sides of a triangle. These ratios in trigonometry relate the ratio of sides of a right triangle to the respective angle. The basic trigonometric ratios are sin, cos, and tan, namely sine, cosine, and tangent ratios.

What are the 3 trig ratios?

Three common trigonometric ratios are the sine (sin), cosine (cos), and tangent (tan).

Who is the father of trigonometry?

Hipparchus

How to prove trigonometric ratios?

The general method of proving trigonometric identities is to work on each side of the equation separately and simplify or manipulate each side until you reach the same expression on both sides.
