Trigonometric Ratios Of Complementary Angles | Class 10 Maths

Описание: 📐 Trigonometric Ratios of Complementary Angles | Class 10 Maths 📚

In this video, we’ll explore one of the most important concepts in trigonometry — Complementary Angles and how their trigonometric ratios are related. Learn how angles that add up to 90° (like θ and 90°–θ) have a special connection between their sine, cosine, tangent, and other ratios.This video lecture is in both Hindi and English.

✅ What you’ll learn:

Meaning of complementary angles in trigonometry

Key identities: sin(90°–θ) = cosθ, cos(90°–θ) = sinθ, etc.Practice examples.


This topic is essential for students of Class 9, 10, 11, 12 and anyone preparing for CBSE, ICSE, JEE, NEET, or other competitive exams.
