Answer:
In mathematics, the determinant is a scalar value that is a function of the entries of a square matrix. It allows characterizing some properties of the matrix and the linear map represented by the matrix.
Step-by-step explanation:
FORMULA
♤ ■The determinant is: |A| = ad − bc or the determinant of A equals a × d minu
s b × c. It is easy to remember when you think of a cross, where blue is positive that goes diagonally from left to right and red is negative that goes diagonally from right to left.
■♤NOTATION
The determinant of a matrix A is denoted det(A), det A, or |A|. Each determinant of a 2 × 2 matrix in this equation is called a minor of the matrix A. ... In geometry, the signed n-dimensional volume of a n-dimensional parallelepiped is expressed by a determinant.
Determinant example
♤■ A determinant is a square array of numbers (written within a pair of vertical lines) which represents a certain sum of products. Below is an example of a 3 × 3 determinant (it has 3 rows and 3 columns). The result of multiplying out, then simplifying the elements of a determinant is a single number (a scalar quantity).
