i have a second-order nonlinear equation with an infinity condition....at first i assume F'(0) like alpha....after finding F(x),i will use pade for F...but i have a problem,cause my condition is F(infinity)=0 and by limiting i cant find alpha because when it goes to zero,it doesnt depend upon what the alpha is..it backs too orders...so...how can i use pade for finding F'(x)?!!!....plz help me:((
