Exercise 7.4    • Exercise 7.4 Class 12 Math || NBF New Book...   Exercise 7.3 Class 12 Math || NBF New Book 2025 || Conic Section Chapter 7 || Point Position & Length of Tangent || by Dr Rizwan In this lecture, we present a complete and detailed solution of Exercise 7.3 from Class 12 Mathematics (National Book Foundation – NBF 2025 Edition), prescribed by the Federal Board of Intermediate and Secondary Education (FBISE), Islamabad, Pakistan. 🕒 Timestamps: 00:00:00 Introduction ‎00:01:40 Question 01 00:10:39 Length of a Tangent Drawn from a Point Lying outside the Circle ‎00:25:29 Question 02 ‎00:28:17 Question 03 ‎00:33:08 Question 04 ‎00:59:33 Question 05 ‎01:14:39 Question 06 ‎01:29:02 Question 07 This is the third exercise of Chapter 7 – Conic Sections, which is a core topic in Analytical Geometry, covering the study of Circle, Parabola, Ellipse, and Hyperbola. These are crucial for both board examinations and university entry tests such as NET, ECAT, and other competitive exams. In this lecture, we focus on two main concepts related to the circle: Determining the position of a point with respect to a given circle — whether it lies inside, on, or outside the circle. Finding the length of the tangent drawn from an external point to the circle. We solve each question from the exercise step-by-step, explaining the logic behind every formula, helping you understand the geometric meaning of algebraic results. 📌 Topics Covered📌 Topics Covered ✔️ Condition to check whether a point lies inside, on, or outside the circle ✔️ Geometrical interpretation of ✔️ Formula for the length of tangent from an external point: ✔️Length of tangent ✔️ Relationship between distance of a point from center and radius ✔️ Conceptual understanding through graphical visualization ✔️ Important exam-style questions and short methods ✔️ Complete Exercise 7.3 Solution (NBF 2025 New Book) 🎯 Best For ✔️ Class 12 Mathematics – Federal Board (FBISE) ✔️ ICS / Pre-Engineering Students ✔️ Entry Test Preparation: NET (NUST), UET, GIKI, FAST, PIEAS, LUMS SSE, COMSATS ✔️ Students seeking conceptual clarity, formula understanding, and exam accuracy 💡 Why Watch This Video?
