Learn how to find the multiplicative inverse of a matrix.

The inverse of matrix is another matrix, which on multiplication with the given matrix gives the multiplicative identity. For a matrix A, its inverse is A⁻¹, and A.A⁻¹ = I. We can calculate the Inverse of a Matrix by: Step 1: calculating the Matrix of Minors, Step 2: then turn that into the Matrix of Cofactors, Step 3: then the Adjugate ...

In this video, we first look at the meaning of the inverse of a matrix. We note that the inverse may not exist for certain matrices (these matrices are called singular matrices; otherwise, a matrix is called invertible if the inverse exists). Then we look at the inverse formula for a (2x2)-matrix. We look at the computation of it. At the end ...
