In some questions I am doing, you set of a pair of simultaneous equations and in the notes we have that . For a non trivial solution of X1 and X2,the determinant of
coefficients of X1 and X2 must be zero.
An equation might typically look like this [itex](m \omega^2 +k_1)x_1 +k_2 x_2=0[/itex]
Why must the determinant be zero? When solving SEs in general using matrices, the determinant must be non-zero?
