## Study Notes

## Linear Algebra: The Language of Vector Spaces

Linear algebra is a branch of mathematics that deals with the manipulation of vectors, matrices, and transformations. It is a powerful tool for solving systems of linear equations and provides a framework for understanding complex relationships between variables.

### Vectors and Spaces

A vector is a mathematical quantity with both magnitude and direction. In linear algebra, vectors are often represented as column matrices, with rows and columns corresponding to the components of the vector. Vectors can also form a vector space, which is a set of vectors that can be combined using operations such as vector addition and scalar multiplication.

### Linear Operations

Linear algebra involves operations that preserve certain properties. For example, an operation is linear if it scales inputs and adds inputs in a predictable way. This includes operations like multiplication and scaling, which are fundamental to linear algebra.

### Matrices and Transformations

Matrices are a key concept in linear algebra. They can be thought of as operations that transform vectors into new vectors. Matrix multiplication is a way of combining matrices and vectors to perform these transformations.

### Linear Dependence and Independence

In linear algebra, vectors can be dependent or independent. If one vector can be written as a linear combination of others, they are dependent. If not, they are independent.

### Linear Mappings and Matrix Algebra

Linear mappings are a way of transforming vectors using matrices. Matrix algebra is the study of these transformations and the properties they satisfy.

### Eigenvectors and Eigenvalues

An eigenvector of a linear transformation is a vector that doesn't change direction when transformed. The eigenvalue associated with an eigenvector represents how much the vector is scaled during the transformation.

Linear algebra has many applications in various fields, including physics, computer graphics, and engineering. It provides a powerful language for understanding and manipulating complex systems of equations and transformations.
