In earlier classes, we have studied the trigonometric ratios of acute angles as the ratio of the sides of a right angled triangle. We have also studied the trigonometric identities and application of trigonometric ratios in solving the problems related to heights and distances. In this
3.1.3 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.

8.1 Introduction. You have already studied about triangles, and in particular, right triangles, in your earlier classes. Let us take some examples from our surroundings where right triangles can be imagined to be formed. For instance : Suppose the students of a school are visiting Qutub Minar.
TRIGONOMETRIC FUNCTIONS. A mathematician knows how to solve a problem, he can not solve it. – MILNE. 3.1 Introduction. The word ‘trigonometry’ is derived from the Greek words ‘trigon’ and ‘metron’ and it means ‘measuring the sides of a triangle’. The subject was originally developed to solve geometric problems involving triangles.
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.
Trigonometric Functions Chapter sets the stage for the comprehensive study of Class 11 1. Mathematics. It serves as a bridge between familiar concepts from lower grades and the more advanced topics covered in the subsequent chapters.
