How Do You Find the Determinant of a 2×3 Matrix?

The determinant is a special number that can be calculated from a square matrix. However, a 2×3 matrix is not a square matrix because it has 2 rows and 3 columns. Since the determinant is only defined for square matrices (matrices with the same number of rows and columns), you cannot find the determinant of a 2×3 matrix.

If you need to find the determinant of a matrix, it must be a square matrix, such as a 2×2 or 3×3 matrix. For example, the determinant of a 2×2 matrix:

| a  b |
| c  d |

is calculated as:

Determinant = (a * d) - (b * c)

For a 3×3 matrix, the calculation is more complex but follows a similar principle. If you have a 2×3 matrix, you would need to either adjust it to a square matrix or use other methods of analysis that do not require the determinant.
