### Vector Spaces

**Concepts Explained:** Vector spaces are fundamental to linear algebra. They provide a framework for understanding linear combinations, span, and basis.

**Example Problem:** Given vectors **v**1â€‹,**v**2â€‹,**v**3â€‹ in a vector space V, determine if they form a basis.

### Matrices

**Concepts Explained:** Matrices are powerful tools for solving systems of linear equations and representing linear transformations. We'll explore types of matrices like square, diagonal, and identity matrices.

**Example Problem:** Find the inverse of the matrix *A*=(12â€‹34â€‹), if it exists.

### Eigenvalues and Eigenvectors

**Concepts Explained:** Eigenvalues and eigenvectors are critical in understanding linear transformations and matrix diagonalization.

**Example Problem:** Calculate the eigenvalues of the matrix *B*=(20â€‹03â€‹).

### Linear Transformations

**Concepts Explained:** Linear transformations are functions between vector spaces that preserve vector addition and scalar multiplication.

**Example Problem:** Show that the transformation *T*(**x**)=*A***x** is linear for a given matrix A.

### Problem-Solving Exercises

**Exercise 1:** Solve the system of linear equations using matrix methods.

**Exercise 2:** Find a basis for the eigenspace corresponding to a given eigenvalue.
