Here you will learn how to find the determinant of matrix 2×2 with examples. Let’s begin – Determinant of Matrix 2×2 If A = \(\begin{bmatrix} a_{11} & a_{12} \\ a_{21} & a_{22} \end{bmatrix}\) is a square matrix of 2×2, then \(a_{11}a_{22} – a_{12}a_{21}\) is called the determinant of A. i.e. | A | = \(\begin{vmatrix} […]
