To show that the limit set for the Poincaré map Xn:= x(2?n), vn:= x’(2?n),where x(t) is a solution to equation (6), is an ellipse and that this ellipse is the same for any initial values x0,v0 , do the following:(a) Argue that since the initial values affect only the transient solution to (6), the limit set for the Poincaré map is independent of the initial values.(b) Now show that for n large, Where And (c) Use the result of part (b) to conclude that the Ellipse contains the limit set of the Poincaré map.
