Conclusion. The inverse of A is A-1 only when A × A-1 = A-1 × A = I. To find the inverse of a 2x2 matrix: swap the positions of a and d, put negatives in front of b and c, and divide everything by the determinant (ad-bc). Sometimes there is no inverse at all.
What Sal introduced here in this video, is a method that was 'woven' specially for finding inverse of a 2x2 matrix but it comes from a more general formula for determining inverse of any nxn matrix A which is: A⁻¹ = 1/det (A) * adj (A) where adj (A) - adjugate of A - is just the transpose of cofactor matrix Cᵀ.
To find the inverse of a 2x2 matrix: swap the positions of a and d, put negatives in front of b and c, and divide everything by the determinant (ad-bc).
The inverse of 2x2 matrix A is a matrix A⁻¹ such that AA⁻¹ = A⁻¹A = I, where I is the identity matrix of order 2x2. Learn more about the inverse of a 2x2 matrix along with its formula, steps, and examples.
