If all the terms of a PDE contain the dependent variable or its partial derivatives then such a PDE is called non-homogeneous partial differential equation or homogeneous otherwise. In the above four examples, Example (4) is non-homogeneous whereas the first three equations are homogeneous. This is an example of an ODE of degree mwhere mis a highest order of the derivative in the equation. Solving an equation like this on an interval t2[0;T] would mean nding a functoin t7!u(t) 2R with the property that uand its derivatives intertwine in such a way that this equation is true for all values of t2[0;T].

Edit: since the upgrade to Mathematica 10, this problem seems solved I just want to solve a system of partial differential equations, for example: $$ \left\{ \begin{array}{l} \frac{\p Definition of Exact Equation. A differential equation of type \[{P\left( {x,y} \right)dx + Q\left( {x,y} \right)dy }={ 0}\] is called an exact differential equation if there exists a function of two variables \(u\left( {x,y} \right)\) with continuous partial derivatives such that Partial Differential Equations.

So, after applying separation of variables to the given partial differential equation we arrive at a 1 st order differential equation that we’ll need to solve for \(G\left( t \right)\) and a 2 nd order boundary value problem that we’ll need to solve for \(\varphi \left( x \right)\). The point of this section however is just to get to this
