"WebA di erential equation is an equation which involves an unknown function f(t) and at least one of its derivatives. Let y= f(t). Then we denote f0(t) as df dt (t) or as y_(t). A general di erential equation is then of the form y_ = F(y(t);t) The purpose of this equation is not to solve for the ariablev t, but rather to solve for the function y(t). " - Dynamic k equation
