WebThe one critical thing to take away from determinants is that if the determinant of a matrix is zero, then the matrix cannot be inverted. WebOct 13, 2024 · In the more general case of a symmetric matrix $$ A= \begin{pmatrix} \color{brown}a & b & c \\ b & \color{brown}d & e \\ c & e & \color{brown}f \end{pmatrix} $$ I quite like the expression for the determinant $$ \det(A) = \color{brown}{adf} - (\color{brown}ae^2 + \color{brown}dc^2 + \color{brown}fb^2)+ 2bce \,. $$ It's got a nice …
