Definition - Determinant of a Matrix
Determinants are scalar quantities and are functions of square matrices. They help to know the nature and inverse of matrices.
A determinant is usually represented with capital alphabets. It is a function of a matrix that gives a singular value.
Formula to find the determinant of the matrix
Square matrices exist in various sizes. Each size has a different formula of determinants. It is not possible to write formulas for all. So below are the formulas for the most common ones.
For a 2x2 matrix
For a 3x3 matrix
The expansion method for the above equation:
How to find determinant of a matrix?
Example
Find the determinant of the following matrix:
Solution:
Step 1: Write down the formula.
= (a x d) - (c x b)
Step 2: Place the values in the equation.
=(4 x 2) - (3 x 6)
= 8 - 18
= -10
