Class 10th Maths Chapter 8.1, "Trigonometry," explores the fundamental relationships between the sides and angles of right-angled triangles��. The chapter introduces trigonometric ratios—sine, cosine, and tangent—and teaches how to apply these ratios to solve problems involving triangles��.Key TopicsIntroduction to Trigonometry: Definition and significance of trigonometry in mathematics and real-life applications��.Trigonometric Ratios: Understanding and calculating the ratios: sine (sin), cosine (cos), and tangent (tan), along with their reciprocal ratios secant (sec), cosecant (cosec), and cotangent (cot)���.Application of Ratios: Solving problems based on given triangle sides, angles, and applying trigonometric identities��.Exercise 8.1 HighlightsFormulae Introduction: Learn the formulae for sin, cos, and tan in the context of right triangles��.Solved Examples: Step-by-step solutions for common trigonometric problems such as finding the value of sin A, cos A, tan A in a given triangle with specific side lengths��.Practice Questions: Varied questions focusing on the application of trigonometric ratios to solve for unknown sides or angles��.Sample Question & SolutionQ1: In triangle ABC, right-angled at B, with AB = 24 cm and BC = 7 cm, determine:
(i) sin A, cos A
(ii) sin C, cos CSolution:AC (hypotenuse) is calculated using Pythagoras theorem: [ AC = \sqrt{(AB^2 + BC^2)} ]�.[ \sin A = \frac{BC}{AC} ], [ \cos A = \frac{AB}{AC} ]�.[ \sin C = \frac{AB}{AC} ], [ \cos C = \frac{BC}{AC} ]�.Trigonometry Importance in Class 10Trigonometry forms the conceptual base for higher mathematics and practical sciences��.This chapter builds a strong foundation for students, enabling analytical and problem-solving skills�.
