Linear algebra is a foundational branch of mathematics that deals with vectors, matrices, determinants, and linear transformations. It plays a crucial role in fields like machine learning, physics, and computer graphics. Let’s break down its core concepts:
🔑 Key Concepts
- Vectors: Quantities with both magnitude and direction (e.g., force, velocity).
- Matrices: Rectangular arrays of numbers used to represent linear equations or transformations.
- Systems of Equations: Solved using matrix operations like Gaussian elimination.
- Eigenvalues & Eigenvectors: Critical for understanding linear transformations’ behavior.
🧮 Practical Applications
- Computer Graphics: Transforming 3D objects into 2D screens via matrices.
- Machine Learning: Used in data representation and algorithms like PCA.
- Quantum Mechanics: State vectors and operators rely heavily on linear algebra.
