摘要: In this note we use a new averaging method, which was introduced in [2], to explain the geometrical behaviour of systems governed by nonlinear boundary value problems formy″+g(y)=K sin(Ωt),y(0)=y(π/Ω)=0. We show numerical computations that global features solutions (such as number solutions, their magnitude, bifurcation behaviour, etc.) agree both original and averaged model. As an example, pendulum equation is discussed detail.
