PB | Class10 | Maths | Chapter 6 | Tribujh_08 (PSEB)

The chapter begins with a brief revision of the trigonometric ratios of sine, cosine, and tangent. Students will then learn about the reciprocal ratios, cosecant, secant, and cotangent, and how to use them to solve problems involving right triangles.

Next, the chapter moves on to the concept of trigonometric identities, which are equations involving trigonometric ratios. Students will learn about some of the important identities such as the Pythagorean identity, sum and difference identities, double angle identities, and half angle identities.

The chapter also covers the application of trigonometry in solving real-life problems. Students will learn how to use trigonometry to find the height and distance of objects and to solve problems related to angles of elevation and depression.

The chapter concludes with a set of exercises that students can use to practice the concepts they have learned. These exercises include problems related to trigonometric ratios, reciprocal ratios, trigonometric identities, and their applications.

Overall, Class 10 Maths Chapter 6 "Trigonometry_08" is an important chapter that lays the foundation for further study of trigonometry in higher classes. It helps students develop problem-solving skills and prepares them for a variety of applications of trigonometry in fields such as engineering, physics, and astronomy.
