The chapter is updated according to the new NCERT, for 2023-2024 Board Exams.

Get NCERT Solutions with videos of all questions and examples of Chapter 8 Class 10 Trigonometry. Videos of all questions are made with step-by-step explanations. Check it out now.

Trigonometry means studying relationship between measures of triangle. Usually, we talk about right triangles when we study trigonometry,

In this chapter, we will study

What is sin, cos, tan ( Sine, cosine, tangent) ... and how they are found in a triangle
What is sec, cosec, cot, and how is it related to sin, cos, tan.
(Sin, cos, tan, sec, cosec, cot are known as Trigonometric Ratios)
Then, we study Trigonometric ratios of specific angles l ike 0°, 30°, 45°, 60°, 90° ; and do some questions
We study the formulas of sin (90 - θ) , cos (90 - θ), tan (90 - θ)
And then we study Trigonometric Identities, and how other identities are derived from sin 2 θ + cos 2 θ = 1
