Trigonometric Functions | Class 11 Maths | Ram Sir | Basics to Advanced | Daily Live 2–2:40 PM

Welcome to LAKHAN JEE 2.0 – Class 11 Mathematics Live Series by Ram Sir 🚀 In this lecture, Ram Suraj Gupta (Ram Sir – M.Sc. Mathematics, NBHM Certificate Holder, Founder of The Gurkul Institute) will teach you the complete basics of Trigonometric Ratios, starting from zero and taking it to the advanced level needed for Class 11 Boards as well as IIT-JEE Foundation. This session is designed to strengthen your fundamentals and build a strong base for higher-level mathematics. 📚 Topics we will cover in this lecture: 1️⃣ Introduction to Trigonometry – Concept of angles, degree measure and radian measure 2️⃣ Definition of trigonometric ratios – sin, cos, tan, cot, sec, cosec 3️⃣ Derivation of ratios from right-angled triangle geometry 4️⃣ Relationship between trigonometric ratios (e.g., tan θ = sin θ / cos θ, etc.) 5️⃣ Standard values of trigonometric ratios (0°, 30°, 45°, 60°, 90°) with proofs 6️⃣ Tricks and tips to remember values quickly 7️⃣ Practice questions for Class 11 Boards 8️⃣ Foundation-level problems for IIT-JEE ✨ Why this lecture is important? 🔹 Builds your fundamentals step by step 🔹 Combines Board Exam preparation with JEE Foundation 🔹 Concepts explained in simple language by Ram Sir 🔹 Interactive problem-solving and doubt-clearing 🔹 Suitable for Class 11 CBSE, ISC, State Boards, and Competitive Exams ⏰ Class Timing: Daily Live from 2:00 PM to 2:40 PM 🏫 Organized by The Gurkul Institute, Bahraich 🔥 About Trigonometry in Class 11 Trigonometry is one of the most crucial topics in Class 11 Mathematics. It is not only important for Board Exams but also forms the foundation of IIT-JEE, NEET, NDA, CUET and other competitive exams. Many advanced concepts in Calculus, Geometry, and Physics are based on trigonometry. Without mastering trigonometric ratios and identities, students often face difficulties in later chapters like Functions, Calculus, and Coordinate Geometry. That’s why this lecture will start with the basics and gradually move towards application-based learning. 📖 Complete Trigonometry Series (Upcoming Lectures by Ram Sir): ✔️ Trigonometric Ratios & Identities ✔️ Trigonometric Equations ✔️ Heights and Distances ✔️ Graphs of Trigonometric Functions ✔️ Applications in Real-Life and Physics Problems Each lecture will be detailed, easy to understand, and exam-focused. 👨‍🏫 About the Teacher – Ram Suraj Gupta (Ram Sir): 🔹 M.Sc. in Mathematics 🔹 Certified by NBHM (National Board for Higher Mathematics) 🔹 Appeared in GATE Exam 🔹 Founder & Managing Director of The Gurkul Institute 🔹 Specializes in IIT-JEE/NEET/Foundation/Board Exam Preparation 🔹 Known for simple explanations, conceptual clarity, and motivating teaching style 👉 Stay Connected: 📌 Subscribe to the channel for more LIVE lectures by Ram Sir 📌 Like, Share, and Comment to support this initiative 📌 Press the Bell Icon 🔔 to get notifications for upcoming sessions 💡 Remember: “Trigonometry is the key to mastering Mathematics.
