Trigonometry

In this chapter, the measurement of angles is discussed. We will learn about the concept of trigonometry here. Positive and negative angles, measuring angles, and the relation between radian and degree are also explained.

This chapter throws light on trigonometric or circular functions. We will understand negative arc length and periodic functions. Trigonometric functions of sum and difference of numbers, multiples of angles, and half angles are also detailed here.

In this chapter, we will understand conditional identities involving the angles of a triangle. We will study three types of identities here—identities involving sines and cosines and their squares, and tangents.

In this chapter, we will acquire knowledge of trigonometric equations. We will understand trigonometric equations and solutions for them. Principal solutions and general solutions of trigonometric equations are also covered here.

This chapter discusses the solutions of triangles. We will learn about the oblique triangle here through figures and diagrams. Problems based on sine and cosine formulas are also provided here.

This chapter introduces students to graphs of trigonometric functions. Here, they will study graphs of various trigonometric functions such as sine, cosine, tan, etc. They are represented through pictures.
