Trigonometry

This chapter discusses the concept of Measurement of Angles. We will learn about the positive and negative angles, the two systems of measuring angles, and the relation between radian and degree.

This chapter focuses 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 described.

This chapter talks about Conditional Identities Involving the Angles of a Triangle. We will learn about the three different forms of identities: involving sines and cosines and their squares and tangents.

In this chapter, we will learn about Trigonometric Equations and functions of unknown angles. It explains these equations and their respective solutions. We also study the principal and general solutions of trigonometric equations.

This chapter explores the Solution of Triangles by discussing its parts. It explains the oblique triangle and provides proofs of theorems on the Sine formula, Cosine formula, etc. It also discusses problems based on Sine and Cosine formulas.

This chapter features the Graphs of Trigonometric Functions. It takes us through the step-by-step method of plotting the graphs for various trigonometric functions represented through pictures.
