CBSE Class 10 Maths – Introduction to Trigonometry

Introduction to Trigonometry is a high-weightage unit in CBSE Class 10 Mathematics carrying approximately 8 marks. It introduces trigonometric ratios for acute angles in right triangles, standard angle values, and algebraic identities.

The chapter covers the six trigonometric ratios (sin, cos, tan, cosec, sec, cot), exact numerical values for 0°, 30°, 45°, 60°, and 90°, and establishing and applying the fundamental identity sin² θ + cos² θ = 1.

Students should master the standard trigonometric values table, learn to convert sec, cosec, tan, and cot into terms of sin and cos, and practise rigorous LHS = RHS identity verification proofs.
