The method can be used to solve both first and second order (special or general form) initial value problem in Ordinary Differential Equation (ODE). This method differs from conventional BDF as derivation is done only once. It can also be extended to solve higher order ODE.enImplicitRunge-kutta TypeInitial value problemsBlockBackward Differentiation Formula (BDF)Article
