Question

what are matrices and determinants

Answer 1

In linear algebra, the determinant is a value that can be computed from the elements of a square matrix. The determinant of a matrix A is denoted det(A), det A, or. ... Determinants occur throughout mathematics.

Answer 2

$\huge\mathfrak{\underline{\underline{\red {matrices}}}}$

Matrix, a set of numbers arranged in rows and columns so as to form a rectangular array. The numbers are called the elements, or entries, of the matrix. Matrices have wide applications in engineering, physics, economics, and statistics as well as in various branches of mathematics.

$\huge\mathfrak{\underline{\underline{\red {determinants}}}}$

In linear algebra, the determinant is a scalar value that can be computed from the elements of a square matrix and encodes certain properties of the linear transformation described by the matrix. The determinant of a matrix A is denoted det(A), det A, or |A|.
