11th Class Mathematics | Chapter 10 – Trigonometric Identities Exercise 10.2 | Question No. 9 (Very Very Important Long Question) 6 Parts | New Book | All Punjab Boards By Sir Ikram Raheem | Learn for Pakistan This lecture covers Exercise 10.2 – Question No. 9, one of the most important long questions of 11th class Mathematics. Almost every Punjab Board includes at least one part of this question in the annual examination, so full preparation is compulsory. Sir Ikram Raheem explains this question step-by-step, using basic identities, quadrant concepts, and logical thinking, so that every student — even weak or average — can solve it confidently in the exam. ⭐ Why Question No. 9 Is Extremely Important ✔ Long question with 6 parts ✔ Appears repeatedly in Punjab Board exams ✔ Tests concept + identity + quadrant knowledge ✔ High-scoring if concepts are clear ✔ One mistake = loss of many marks That is why this lecture must be watched, practiced, and revised. 📐 Core Concepts Covered in This Question In this lecture, you will master: • Understanding given trigonometric ratios • Using conditions like α less than 2π or angle range • Identifying the correct quadrant of α • Deciding the sign (+ / −) of trigonometric functions • Converting one ratio into others • Applying identities correctly 🧠 Identities Used & Explained Clearly Sir Ikram Raheem explains why and how to use: • sin²α + cos²α = 1 • cos²α = 1 − sin²α • sin²α = 1 − cos²α • tanα = sinα / cosα • secα = 1 / cosα • cosecα = 1 / sinα No confusion — every step is logical and exam-friendly. 🧭 Quadrant Concept (Most Students’ Weak Area) This lecture gives special focus on quadrants: • Which quadrant α lies in • Which functions are positive or negative • How quadrant changes the final answer • Why ignoring quadrant causes wrong answers After this lecture, quadrants will never confuse you again. ✍️ Exam-Oriented Solving Method You will learn: • How to start each part properly • How to select the correct identity • How to simplify without skipping steps • How to present answers like a topper • How to avoid common board mistakes This method helps you secure full marks. 🎯 For Every Type of Student This lecture is perfect for: • Toppers aiming for 90+ • Average students who fear trigonometry • Backbenchers who forget formulas • Repeaters preparing again • Students of academies & colleges Sir Ikram Raheem teaches slow, clear, and from basics. 🏫 Valid for All Punjab Boards Applicable for students of: Lahore, Gujranwala, Faisalabad, Multan, Sahiwal, Bahawalpur, Rawalpindi, DG Khan, Sargodha, Khanewal and all Punjab Boards. 🇵🇰 My Mission – Learn for Pakistan This is not just a YouTube channel.
