11th Math Chapter 10 || Ex 10.1 || Sir Ikram || Learn For Pakistan

Welcome to your own classroom — Learn For Pakistan — where mathematics is taught in the easiest, cleanest and most understandable way for every student of Punjab. In this lecture, we solve Chapter 10 – Trigonometric Functions & Identities – Question No. 1, where we find the values of angles like: ✔ sin 110° ✔ cos (–123°) ✔ sin 1180°, cos 1260°, etc. WITHOUT using a calculator — only with concept + quadrant + identities. This is an important short question for all Punjab Boards (Lahore, Multan, Gujranwala, Sahiwal, DG Khan, Sargodha, Faisalabad, Rawalpindi, Bahawalpur, Federal Board). 🔥 What You Will Learn in This Lecture This lecture is full of concepts, including: ✔ 1. How to reduce big angles • Convert 1100°, 1180°, 1260°, etc. using → 360° rule → 180° rule So the angle becomes small and easy. ✔ 2. How to work with negative angles • cos(–123°) = cos(123°) (because cos is even) • sin(–θ) = –sin(θ) (odd function) ✔ 3. Complete Quadrant Concept You will fully understand: 1st Quadrant → All are positive 2nd Quadrant → Only Sin & Cosec positive 3rd Quadrant → Only Tan & Cot positive 4th Quadrant → Only Cos & Sec positive This method helps you find the sign of any trigonometric ratio easily. ✔ 4. How to move angle into another quadrant When we add or subtract 90°, 180°, or 360°: • Add 90° → Angle moves to next quadrant • Add 180° → Angle moves to opposite quadrant • Add 360° → Angle returns to same quadrant You also learn when the trigonometric function changes (like sin becomes cos, cos becomes –sin, etc.). ✔ 5. How to find the reference angle Find the basic acute angle (like 30°, 45°, 60°) and then apply the sign from the correct quadrant. ✔ 6. Pure exam-targeted solution Every question is solved step-by-step with clear logic, perfect for short questions and MCQs. 🌟 Why This Lecture is Important ✔ Highly important for Punjab Boards ✔ Very common question in short questions ✔ Perfect for preparation of Mid-term + Final term ✔ You will learn how to solve any angle without calculator ✔ Very easy and fast method — even weak students can master it 🌟 Why Students Love This Classroom This is not just a YouTube channel. This is your classroom. Here, every student can learn: ✔ In easy words ✔ With simple steps ✔ With visual logic ✔ With real understanding, NOT memorization ✔ With practical examples ✔ With full clarity and confidence Even an average or weak student becomes strong when the method is easy. 🇵🇰 My Mission for the Students of Pakistan I, Sir Ikram Raheem, teach with a purpose: • No student should fail • Every student should understand, not cram • Every student should work for their future, family and Pakistan • Give students real confidence • Build strong concepts, not shortcuts • Create a generation that learns, thinks and grows • Replace reels with education • Give real freedom through knowledge Join the mission of Educated Pakistan. 📢 What You Should Do 👉 Subscribe to join the classroom 👉 Like the video to support the mission 👉 Comment your questions — this class is for you 👉 Share with your friends — help them pass 👉 Watch full lecture for perfect understanding Your success is my mission.
