How to Find the Intersection Line of 2 Planes | Vectors - IB Mathematics

Master position and displacement vectors with this essential lesson for IB and IGCSE Mathematics! This video breaks down the fundamental concepts you need to solve vector geometry problems with confidence. 📌 What you’ll learn: Position Vectors: How to define a point relative to the origin (O). Displacement Vectors: Calculating the movement between any two points. The Coordinate Formula: Finding vectors using (x2 − x1,y2 - y1)​ The Subtraction Rule: Why AB = OB − OA is the most important formula in vector geometry. Vector Addition: Understanding Chasles’ Rule (The Triangle Law). ⏳ Timestamps: [00:00] Introduction [00:34] What are Position Vectors?
