24 Nov 2017 One distinguishes between ordinary differential equations (ODE) and partial differential equations (PDE). While ODE contain only derivatives with respect to one variable, PDE can contain (partial) derivatives with respect to several different variables. In general,. PDE are much harder to solve than ODE.
Mathematics is a part of physics. Physics is an experimental science, a part of natural science. Mathematics is the part of physics where experiments are cheap. In the middle of the twentieth century it was attempted to divide physics and mathematics. The consequences turned out to be catastrophic. Whole generations of
Definition: A differential equation is an equation which contains derivatives of the unknown. (Usually it is a mathematical model of some physical phenomenon.) Two classes of differential equations: • O.D.E. (ordinary differential equations): linear and non-linear;. • P.D.E. (partial differential equations). (not covered in

Department of Mathematics. Leipzig . more complicated in the case of partial differential equations caused by the fact that Equation. F(x, y(x),y (x),,y(n))=0 is an ordinary differential equation of n-th order for the unknown function y(x), where F is given. An important problem for ordinary differential equations is the initial.
