6. Inverse of Matrix using Elementary Transformations (Row Operations) | Class 12 & Engineering

Finding the Inverse of a Matrix using Elementary Row Operations (ERO) is often considered the toughest topic in Class 12 Matrices. One small calculation mistake, and the whole answer is wrong! 😫 In this video, Er Anand shares a Secret Algorithm (The U-Turn Method) to solve these problems systematically without getting stuck. 🛡️ WHAT YOU WILL MASTER: ●Elementary Operations: The 3 valid operations for Rows () and Columns () - Swapping, Scaling, and Adding.37 ●Invertible Matrices: Condition for existence of inverse (). ●The Strategy: How to convert Matrix into Identity Matrix step-by-step (). ●The "One-Zero" Trick: The exact order in which you should create 1s and 0s to avoid undoing your previous steps.36 💡 THE "U-TURN" TECHNIQUE: Don't solve randomly! We teach you to move column by column: 1.Col 1: Make , then others 0. 2.Col 2: Make , then others 0. 3.Col 3: Make , then others 0.
