WebWell, for a 2x2 matrix the inverse is: a b c d −1 = 1 ad−bc d −b −c a In other words: swap the positions of a and d, put negatives in front of b and c, and divide everything by ad−bc . Note: ad−bc is called the determinant. Let us try an example: 4 7 2 6 −1 = 1 4×6−7×2 6 −7 −2 4 = 1 10 6 −7 −2 4 = 0.6 −0.7 −0.2 0.4 Websymmetric matrix to be negative definite or neither. Before starting all these cases, we recall the relationship between the eigenvalues and the determinant and trace of a matrix.
