Linear algebra is the branch of mathematics concerning vector spaces and linear mappings between such spaces. It includes the study of lines, planes, and subspaces, but is often more general and abstract. Linear algebra is central to both pure and applied mathematics, especially in developing other mathematical disciplines such as algebra, geometry, and analysis.
Key Concepts
- Vector Spaces: A vector space is a collection of objects called vectors, which may be thought of as arrows or directed line segments, each having a definite magnitude and direction.
- Matrices: A matrix is a rectangular array of numbers, used to represent systems of linear equations and transformations.
- Determinants: A determinant is a scalar value that can be computed from the elements of a square matrix and encodes certain properties of the matrix.
Applications
Linear algebra has many applications in various fields, including:
- Computer Graphics: Linear algebra is used to model and manipulate 3D objects, such as in video games and animation.
- Machine Learning: Linear algebra is used to represent and manipulate data in machine learning algorithms.
- Physics: Linear algebra is used to describe the motion of objects and the behavior of forces.
