Systems of ordinary differential equations Last two lectures we have studied models of the form y′(t) = F(y), y(0) = y0 (1) this is an scalar ordinary differential equation (ODE). In the next two lectures we shall study systems of ODEs. Especially we will consider numerical methods for systems of two ODEs on the form y′(t) = F(y,z), y(0) = y0,
