What's the difference between numerical method tocalculate differential (backward, central, forward)? At whatcondition do I have to use forward over central and backward, etc?If there's boundary condition that permits the complete use ofcentral method, what will happen if I still use forward, backward,and central regardless there's boundary condition that permits theuse of central method?
note: I'm not used to describe pure mathematical problem inenglish, so I'm sorry if my question is hard to understand. feelfree to add comment under this question and I'll explain it again,hopefully in clearer manner. thank you
