Determinant of Order Two

Advertisement Remove all ads



`|[a,b],[c,d]|` is a determinant. (a, b), (c, d) are rows and `([a],[c]), ([b],[d])` are columns.

Degree of this determinant is 2, because there are 2 elements in each column and 2 elements in each row. Determinant represents a number which is (ad-bc).

ad-bc is the value of determinant `|[a,b],[c,d]|`

Determinants, usually, are represented with capital letters as A, B, C, D, . . . . . etc.

Example: Find the values of the following determinant. 



`A=|[5,3],[7,9]| = (5xx9)-(3xx7)=45-21=24`
