trigonometric ratios in solving the problems related to heights and distances. In this Chapter, we will generalise the concept of trigonometric ratios to trigonometric functions
Trigonometric ratios are defined for acute angles as the ratio of the sides of a right angled triangle. The extension of trigonometric ratios to any angle in terms of radian measure (real numbers) are called trigonometric functions. The signs of trigonometric functions in different quadrants have been given in the following table:

1. What are the basic trigonometric functions? Ans. The basic trigonometric functions are sine (sin), cosine (cos), and tangent (tan). These functions relate the angles of a right triangle to the lengths of its sides. 2. How are sine and cosine related to each other? 3. What is the unit circle and how is it related to trigonometric functions? 4.

The word ‘trigonometry’ is derived from the Greek words ‘tri’ (meaning three), ‘gon’ (meaning sides) and ‘metron’ (meaning measure). In fact, trigonometry is the study of relationships between the sides and angles of a triangle. The earliest known work on trigonometry was recorded in Egypt and Babylon.
Chapter 3 Trigonometric Functions of NCERT Solutions for Class 11 Maths covers the complex topics of trigonometric functions and their uses. This chapter consists of 4 sub-sections which deal with topics like measuring angles in radians and degrees and their interconversion.
