A Matrix is a rectangular array of mathematical elements: numbers, symbols or expressions, that can be combined to form sums and products with similar arrays having an appropriate number of rows and columns.
Determinant of a 2x2 Matrix
[Math| Linear Algebra| Matrix] This equation is used to find the determinant of a 2-by-2 matrix. To find the determinant of the 2-by-2 matrix you first multiply the elements from the top left to the bottom right corner and subtract the product from top right to the bottom left. The determinant is most often used to find the nature of solution of the system of linear equations defined by the matrix. This equation is only used for a 2-by-2 matrix, it cannot be used for matrices that are 3-by-3, 4-by-4, etc.
