Project 3.1 Ma226 In order to solve the differential equation with two parameters we solved for the Eigen values. dx/dt = ax + by dy/dt = -x –y In matrix form, a b x 0 -1 -1 y = 0 To solve the eigen values we get the characteristic equation: J^2 – (a-1)J + (-a+b) Apply the quadratic formula and solve for J
