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). WebDynamic System Response, Page 3 o For nonhomogeneous ODEs (those with non-zero right hand sides) like the above, the solution is the sum of a general (homogeneous) part and a particular (nonhomogeneous) part in which the right hand side takes the actual form of the forcing function, x(t) times K, namely y t ygeneral particular t y t .
