- Homework Statement
- determine the order of the given partial differential equation;also state whether the equation is linear or nonlinear

- Relevant Equations
- The ordinary differential equation is said to be linear if F is a linear function of the variables y,y,...,y(n); a similar definition applies to partial differential equations.

The order of a differential equation is the order of the highest derivative that appears in the equation.

ok I posted this a few years ago but replies said there was multiplication in it so I think its a mater of format

##\dfrac{\partial u^2}{\partial x\partial y}## is equivalent to ##u_{xy}##
