NCERT Solutions for Class 10 Maths Chapter 8:Important Topics The word trigonometry is derived from the Greek words ‘tri’ (meaning three), ‘gon’ (meaning sides), and ‘metron’ (meaning measure). Trigonometry is the study of relationships between the sides and angles of a triangle. Today, most of the technologically advanced methods used in Engineering and Physical Sciences are based on trigonometric concepts. This branch of Mathematics, called Trigonometry, is extremely helpful in dealing with height and distances, which are not easy to measure. In this article, we have provided NCERT Solutions for Class 10 Maths Chapter 8 which will help students understand the topics, complete their in-text exercises, and work on their doubts. Before delving further into the details, students...

NCERT Solutions for Class 10 Maths Chapter 8 "Introduction to Trigonometry" contains four exercises. Below is a brief explanation of each exercise: Exercise 8.1 - In this exercise, students are introduced to the basic trigonometric ratios - sine, cosine, and tangent, and their reciprocal functions. They learn how to find the values of these ratios for acute angles in a right triangle. The exercise also covers the concept of trigonometric identities, which are fundamental relationships between trigonometric functions. Exercise 8.2 - This exercise deals with the application of trigonometric ratios to solve real-life problems. Students learn how to use trigonometric ratios to find the height and distance of an object, as well as the angle of elevation and depression. They also learn how to use the Pythagorean theorem to solve problems involving right triangles. Exercise 8.3 - In this exercise, students learn about complementary angles and how to find the trigonometric ratios of complementary angles. They also learn about the trigonometric ratios of angles greater than 90 degrees and less than 0 degrees, and how to find their values using the reference angle. Exercise 8.4 - The final exercise covers the concept of trigonometric equations. Students learn how to solve trigonometric equations using the identities and ratios learned in the previous exercises. They also learn how to find the general solution of a trigonometric equation, which involves finding all the possible solut...
