The concept of the inverse of a matrix involves a corresponding matrix that, when multiplied by the original matrix, yields the identity matrix. The common method for determining the inverse incorporates the formula: inverse of A = 1/det(A) * adj(A), where the determinant is represented by det(A) and adj(A) represents the adjugate of A.
