Amr Morsi Posted October 21, 2011 Share Posted October 21, 2011 Modelling is a very specific extraordinary section in Mathematics. Although many systems can only be described by partial differential equations, and may be tensors equations, they can be modeled, approximately and even in some cases exactly, by very simpler equations, O.D.E.s and may be Vector Field Multi-Dimensional Functions, just assume the variables you are not in need for, pick up the property you are in need, and derive the equation. For example, conservative field force are described by an O.D.E. (or P.D.E. in the sense of general force form), but can be analyzed very simply by the form of Potential. If there is some thing wrong, would some one advise? Link to comment Share on other sites More sharing options...
