**Introduction**

Trigonometry is the study of triangles, particularly those with right angles (90°). It involves the relationships between the angles and side lengths of triangles. Trigonometry is used to solve problems that involve waves, sound, light, and many other phenomena in science and engineering.

**Key Concepts**

1. **Angles and Triangles**: Understanding the different types of angles (acute, obtuse, right, straight, reflex) and their relationships with each other.
2. **Trigonometric Ratios**: Introducing the six basic trigonometric ratios: sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc).
3. **Trigonometric Identities**: Learning the fundamental identities, such as sin(A + B) = sin(A)cos(B) + cos(A)sin(B), and their applications.
4. **Trigonometric Functions**: Understanding the behavior of trigonometric functions, including their periodicity, amplitude, and phase.
5. **Graphs of Trigonometric Functions**: Plotting the graphs of trigonometric functions, including sine, cosine, and tangent.
6. **Applications of Trigonometry**: Exploring the applications of trigonometry in real-life scenarios, such as navigation, physics, and engineering.

**Important Formulas**

1. sin(A) = opposite side / hypotenuse
2. cos(A) = adjacent side / hypotenuse
3. tan(A) = opposite side / adjacent side
4. csc(A) = hypotenuse / opposite side
5. sec(A) = hypotenuse / adjacent side
6. cot(A) = adjacent side / opposite side

**Solved Examples**

The chapter includes numerous solved examples that illustrate the application of trigonometric concepts to solve problems in various contexts.

**Practice Problems**

The chapter concludes with a set of practice problems that help students reinforce their understanding of trigonometric concepts and develop problem-solving skills.

**Key Takeaways**

By the end of this chapter, students should be able to:

* Understand the basic trigonometric ratios and their relationships
* Apply trigonometric identities to solve problems
* Analyze the graphs of trigonometric functions
* Use trigonometry to solve problems in real-life scenarios

Overall, Chapter 8: Trigonometry in Class 10 Maths provides a solid foundation for understanding the fundamental concepts and applications of trigonometry.
