Students are introduced to the concept of Trigonometry through NCERT Grade 10 Mathematics, Chapter 8, Introduction to Trigonometry. In this chapter, students will study some ratios of the sides of a right triangle with respect to its acute angles, called trigonometric ratios of the angle. They will restrict the discussion to acute angles only. However, these ratios can be extended to other angles also. Students will also learn to define the trigonometric ratios for angles of measure 0° and 90°. They will calculate trigonometric ratios for some specific angles and establish some identities involving these ratios, called trigonometric identities.
Trigonometric Ratios, Trigonometric Ratios of Some Specific Angles, Trigonometric Ratios of Complementary Angles and Trigonometric Identities are the main topics learnt from this chapter. A very simple language, explanation of basic concepts in a detailed manner and pictorial representations make this chapter very engaging and interesting to learn. New concepts, interesting problems, solved and unsolved examples and simple language, make NCERT Grade 10 Mathematics, Chapter 8, Introduction to Trigonometry interesting and fun to learn. The chapter also provides additional information through contribution of eminent mathematicians to the world of Mathematics. All these elements add spice to the learning experience of the students so that they enjoy learning Trigonometry.
