**CBSE NCERT Solutions For Class 11 Maths Chapter 3 – Trigonometric Functions– Chapter Summary**

The word **‘Trigonometry’** is derived from the Greek words **‘trigon’ **and** ‘metron’. **It means **‘measuring the sides of a triangle’**. The subject was developed to solve geometric problems involving triangles. It was studied by sea captains for navigation, surveyor to map out the new lands, by engineers and others. Currently, trigonometry is used in many areas such as the science of seismology and designing electric circuits. Describing the state of an atom, predicting the heights of tides in the ocean and analyzing a musical tone are other areas.

In earlier classes, you have studied the **trigonometric ratios** of acute angles as the ratio of the sides of a right-angled triangle. In this chapter, the concept of trigonometric ratios to trigonometric functions has been explained. Hence, students will study their properties in a comprehensive way. In the beginning, you will learn about radian measure – conversion, arc length and finding the value of trigonometric functions. Next, Finding the value of trigonometric functions, given angle, (x + y) formula will be explained. Additionally, you will learn general solutions, sine, cosine, and other **trigonometry formulas** in this chapter.
