## What is elementary linear algebra?

Before we dive into the details of the book, let us first review what elementary linear algebra is and why it is important. Elementary linear algebra is the introductory level of linear algebra that covers the basic concepts and techniques that are essential for further study and application of the subject. It does not require much prior knowledge of mathematics, except some familiarity with algebra and geometry.

### Definition and examples of linear algebra

Linear algebra is the branch of mathematics that studies linear objects and linear transformations. A linear object is something that can be added or multiplied by a scalar (a number) without changing its essential properties. For example, vectors are linear objects because they can be added or scaled without affecting their direction or magnitude. A vector is an ordered list of numbers that represents a point or a direction in a coordinate system. For example, (2, 3) is a vector that represents a point in a two-dimensional plane.

A linear transformation is a function that maps one linear object to another while preserving their linearity. For example, rotation is a linear transformation because it maps one vector to another without changing its length or angle. A matrix is a rectangular array of numbers that represents a linear transformation. For example, [[0,-1],[1,0]] is a matrix that represents a 90-degree clockwise rotation in a two-dimensional plane.

Linear algebra studies various properties and operations of linear objects and transformations, such as addition, subtraction, multiplication, division, inverse, transpose, determinant, rank, trace, eigenvalues, eigenvectors, orthogonality, diagonalization, decomposition, etc. It also studies various types and structures of linear objects and transformations, such as vector spaces, subspaces, bases, dimensions, span, linear independence, linear dependence, null space, column space, row space, kernel, image, domain, codomain, range, linear equations, systems of linear equations, homogeneous equations, non-homogeneous equations, consistent equations, inconsistent equations, augmented matrices, reduced row echelon form, Gaussian elimination, Gauss-Jordan elimination, matrix equations, vector equations, linear combinations, linear independence, linear dependence, linear functionals, linear operators, linear mappings, matrices, square matrices, rectangular matrices, identity matrices, zero matrices, diagonal matrices, scalar matrices, upper triangular matrices, lower triangular matrices, etc.

### Applications and importance of linear algebra

Linear algebra has many applications and importance in various fields of science, engineering, computer science, economics, and more. Here are some examples of how linear algebra is used in different domains:

In physics, linear algebra is used to model physical phenomena such as forces, motions, rotations, vibrations, waves, optics, quantum mechanics, relativity, etc.

In chemistry, linear algebra is used to model molecular structures, chemical reactions, spectroscopy, thermodynamics, etc.

In biology, linear algebra is used to model biological systems, such as genetics, population dynamics, ecology, bioinformatics, etc.

In engineering, linear algebra is used to design and analyze systems and structures, such as circuits, networks, signals, control systems, robotics, etc.

In computer science, linear algebra is used to develop and implement algorithms and data structures, such as graphics, image processing, computer vision, machine learning, artificial intelligence, cryptography, etc.

In economics, linear algebra is used to model and optimize economic problems, such as production functions, utility functions, demand functions, supply functions, market equilibrium, game theory, linear programming, etc.

As you can see, linear algebra is a very powerful and versatile tool that can help you understand and solve many real-world problems. It is also a foundation for many advanced topics in mathematics and other disciplines. Therefore, learning linear algebra is not only useful but also essential for anyone who wants to pursue a career or a hobby in science, engineering, computer science, economics, or any other field that involves mathematics.
