Your method: y1 = y0 +h*f(x0,x0+h*f(x0,y0)) Your method is not backward Euler. You don't solve in y1, you just estimate y1 with the forward Euler method. I don't want to pursue the analysis of your method, but I believe it will behave poorly indeed, …

WebForward Euler takes a step along the derivative at the current time and position. The backward Euler method uses almost the same time stepping equation: k = hf(t+ h;x+ k) Backward Euler chooses the step, k, so that the derivative at the new time and position is consistent with k.
