Here is a collection of Lay Problems in Linear Algebra. These problems are designed to help you understand the concepts and applications of linear algebra.

Introduction

Linear algebra is a branch of mathematics that deals with linear equations, linear transformations, and vector spaces. It has wide applications in various fields such as physics, engineering, computer science, and economics.

Problem Set

  1. Matrix Representation
    Find the matrix representation of the linear transformation ( T ) that rotates a point in the plane by 90 degrees counterclockwise.

  2. Eigenvalues and Eigenvectors
    For the matrix (\begin{bmatrix} 4 & 2 \ 2 & 1 \end{bmatrix}), find the eigenvalues and eigenvectors.

  3. Solving Systems of Linear Equations
    Solve the following system of linear equations:
    [ \begin{cases} 2x + 3y = 8 \ x - y = 1 \end{cases} ]

  4. Determinants
    Calculate the determinant of the matrix (\begin{bmatrix} 1 & 2 & 3 \ 4 & 5 & 6 \ 7 & 8 & 9 \end{bmatrix}).

  5. Change of Basis
    Find the change of basis matrix from the standard basis to the basis ({(1, 2), (3, 4)}).
