Wrath of Math | Determine if 2x2 Matrix is Invertible @WrathofMath | Uploaded 2 months ago | Updated 5 hours ago
We go over how to identify invertible 2x2 matrices. Given a 2x2 matrix, we can determine if the matrix is invertible by computing the determinant. The determinant, which is the difference of the products of the diagonals, must be nonzero for the matrix to be invertible. If the determinant is 0 then the matrix is not invertible. #linearalgebra
