Class 10 Maths Exercise 8.1 focuses on introducing basic trigonometric ratios like sine, cosine and tangent. To prepare, begin by thoroughly understanding the definitions and relationships between the sides of a right-angled triangle. Memorise the trigonometric ratios of commonly used angles (like 30°, 45°, 60°) as they frequently appear in both theoretical and practical problems. Practice deriving values for trigonometric ratios by applying the Pythagorean theorem where necessary.
Start by solving simpler problems, such as finding missing sides or angles in right triangles using given trigonometric ratios. Gradually move on to more complex problems involving multiple steps. It’s crucial to practice a variety of problems to get comfortable with the application of these ratios in different scenarios. Regular revision of the identities and their application will help solidify your understanding and improve problem-solving speed for the exam.
