(3) gives the expression (4) which is called the determinant for this system of equation. Determinants are defined only for square matrices. If the determinant of a matrix is 0, the matrix is said to be singular, and if the determinant is 1, the matrix is said to be unimodular....

In a 4 x 4 matrix, the minors are determinants of 3 X 3 matrices, and ann x nmatrix has minors that are determinants of(n - 1) X (n - 1)matrices. To find the determinant of a 3 X 3 or larger matrix, first choose any row or column. Then the minor of each element in that ...
A Matrix (This one has 2 Rows and 2 Columns) Let us calculate the determinant of that matrix: 3×6 − 8×4 = 18 − 32 =−14 Easy, hey? Here is another example: Example: B = 1234 Thesymbolfor determinant is two vertical lines either side like this: ...
The determinant of a 2×2, 3×3, and 4×4 matrix As it often is in life, size matters. In this particular case, the smaller the matrix, the easier the determinant formula. For consistency, we use the notation below, as in the matrix determinant calculator. If A=[a1a2b1b2]A=[a1b1...

Determinant of a Matrix is a number that is specially defined only for square matrices. Determinants are mathematical objects that are very useful in the analysis and solution of systems of linear equations. Determinants also have wide applications in En
This lesson shows how to calculate the determinant of any square matrix. Introduces notation for matrix determinants. Includes problems with solutions.
