Ever wondered how computers, artificial intelligence, and even 3D graphics work? The answer lies in matrices – those mystical grids of numbers that can bend reality (okay, maybe not reality, but definitely equations)! NCERT Class 12 Maths Chapter 3, Matrices, is all about understanding these powerful mathematical tools.
Don’t worry; this chapter won’t turn you into Neo from The Matrix, but it will definitely make you a math wizard! 🧙♂️ Let’s dive into the exciting world of matrices with a fun and easy-to-understand approach.
NCERT Class 12 Maths Chapter 3. Matrices📌 What is a Matrix? – More Than Just a Fancy Table!
A matrix (plural: matrices) is nothing but a rectangular arrangement of numbers, symbols, or expressions in rows and columns. Think of it like a WhatsApp group chat, where:
- Rows are like different conversation threads.
- Columns are the participants in the group chat.
Each number in a matrix is called an element, just like every person in a WhatsApp group has a role (some active, some just lurking 👀).
Example of a Matrix:
A=[123456789]A = \begin{bmatrix} 1 & 2 & 3 \\ 4 & 5 & 6 \\ 7 & 8 & 9 \end{bmatrix}
This is a 3×3 matrix (3 rows and 3 columns).
