【Abstract】 In many published papers such like [1], [2], [3], [4] numerical methods for solving differential equation yn = f(x,y) and its stability are investigated. The content of this paper is to give a general optimal method for solving such special equation. Furthermore for the cases k= 2, 4, 6, 8,10 optimal methods are constructed, which contain the largest periodic stability interval.更多还原
