Linear algebra is a branch of mathematics which is normally not included in the standard high school curriculum. A notable part of linear algebra concerns the properties of matrices and determinants. In short, matrices are usually expressed as arrays of numbers, where the numbers have been arranged in rows and columns. In a square matrix the numbers of rows and columns are the same, and for every square matrix one may calculate a number, which is known as the determinant of the matrix. Matrices and determinant have various applications, but in this course they are basically applied in the solution of the linear systems of equations. The student learns the basic operations of matrices and determinants, and to solve by means of them linear systems of equations. A concept, which is closely related to matrices, is vector. Vectors are used to describe quantities which, in addition to magnitude, are also associated with direction. In this course the student learns the basics of vector calculus, and to apply vectors when solving simple geometrical problems. In addition, the course involves an extension of basic trigonometry, and provides the basic knowledge on complex numbers and their expressions in the polar form. The last part of the course concerns inequalities.
