In this video, we will solve Exercise 6.2 Question 4 & 5 from Class 9th New Mathematics, Chapter 6 — Trigonometry. The main focus of this lesson is on Trigonometric Ratios of Complementary Angles. Complementary angles are two angles whose sum is 90 degrees, and understanding their trigonometric relationships is essential for mastering this chapter. We will explain the concept with simple formulas like sin(90°−θ) = cos(θ) and cos(90°−θ) = sin(θ), making it easier for students to grasp the logic. This step-by-step solution is designed according to the latest Punjab Textbook Board syllabus (PTB), ensuring you are fully prepared for your board exams. Whether you are a student struggling with trigonometry or a teacher looking for easy teaching methods, this video will clarify all your doubts regarding complementary angles and their trigonometric ratios.
