Artham Resources presents simplified and structured topic-wise notes for Chapter 8: Introduction to Trigonometry, aligned with the CBSE Class 10 syllabus. The notes begin with the concept of trigonometric ratios (sine, cosine, tangent, and others), defined using right-angled triangles. Each ratio is explained with diagrams, helping students understand their meaning and application. The notes cover the trigonometric ratios of specific angles (0°, 30°, 45°, 60°, 90°) and their identities, including the most important identity:
$\sin^2 \theta + \cos^2 \theta = 1$.
Real-life examples, solved numerical, and short tricks make learning engaging and effective. Students also learn how to apply these ratios in problem-solving and simplify expressions using identities. With quick revision notes, formula boxes, and concept snapshots, this resource is perfect for boards and practice.
