Trigonometric Identities Equalities involving trigonometric functions are known as Trigonometric Identities, and they hold for all values of the variables involved, defining both sides of the equality. We'll look at Trigonometric Identities in this mini-lesson. The three primary trigonometric ratios are sin, cos, and tan. The reciprocals of sin, cos, and tan are the three other trigonometric ratios in trigonometry: sec, cosec, and cot. What is the relationship between these trigonometric ratios (sin, cos, tan, sec, cosec, and cot)? Trigonometric Identities bind them together (or in short trig identities). In the following sections, we'll look at the Tri...

NCERT Solutions Class 10 Maths Chapter 8 Introduction to Trigonometry NCERT solutions for class 10 maths chapter 8 Introduction to Trigonometry builds on the concept of a right triangle and introduces students to the basics of trigonometry. The word ‘trigonometry’ is derived from the Greek words ‘tri’ (meaning three), ‘gon’ (meaning sides), and ‘metron’ (meaning measure). Trigonometry can be defined as the study of relationships between the sides and angles of a triangle. There are two main concepts that students will learn in this chapter, which are, trigonometric ratios and trigonometric identities. Most of the technologically advanced methods used in Engineering and Physical Sciences are based on trigonometric concepts making it an extremely important lesson. This is one of the most scoring topics in the board examinations provided they go through the topic with diligence and in an organized manner. These concepts are also used in sister topics of higher classes such as calculus and geometry.
