Witryna20 gru 2024 · 2. You should rather compare both solutions with exp (t) and re-evaluate your question. – Peter Meisrimel. Dec 20, 2024 at 19:06. 1. You are comparing (1+h)^n = 2^n with (1+h+h^2/2)^n=2.5^n which obviously will give different, rapidly diverging results. The second will be closer to e^n= (2.7182818284...)^n but still rather different. Witryna1 lis 1988 · The new improved Euler methods given here offer several advantages for the solution of ordinary differential equations. The explicit form is of second-order global accuracy but requires only one derivative evaluation per step. It is therefore more efficient than either simple Euler or Runge—Kutta two. how do you introduce your company
