determinants of matrix 3×3

Here you will learn how to find determinants of matrix 3×3 with examples. Let’s begin – Determinants of Matrix 3×3 If A = \(\begin{bmatrix} a_{11} & a_{12} & a_{13} \\ a_{21} & a_{22} & a_{23} \\ a_{31} & a_{32} & a_{33} \end{bmatrix}\) is a square matrix of order 3, then \(a_{11}(a_{22}a_{33} – a_{23}a_{a32})\) – \(a_{12}(a_{33}a_{21} […]
