Class 10 Maths NCERT Introduction to Trigonometry
The Introduction to Trigonometry chapter of Class 10 NCERT Mathematics introduces students to the basic concepts of trigonometric ratios and their applications in right-angled triangles. Students learn about six fundamental trigonometric ratios—sine (sin), cosine (cos), tangent (tan), cosecant (csc), secant (sec), and cotangent (cot)—and how they relate to the sides of a right-angled triangle.
The chapter explains how to use these ratios to solve problems involving unknown sides or angles in triangles, along with practical examples and solved exercises. Students also learn about the reciprocal and quotient identities, which help simplify trigonometric expressions.
By practicing the exercises in the NCERT textbook, students develop strong problem-solving, analytical, and logical reasoning skills. The Class 10 Maths NCERT Introduction to Trigonometry chapter is essential for CBSE exams and lays the foundation for advanced trigonometry in higher classes and competitive exams.
