First, we know how to solve the system (??) by finding the eigenvalues and eigenvectors of the coefficient matrix in (??). Second, we know from the general theory of planar systems that solutions will have the form for some scalar . WebSo if this is 0, c1 times 0 is going to be equal to 0. So this expression up here is also equal to 0. Or another way to view it is that if g is a solution to this second order linear homogeneous differential equation, then some constant times g is also a solution. So this is also a solution to the differential equation. portland fun things to do
