Math & Science ⇒ Overfull error message

[Ntande1]

Hi
Please help me with the code below, Latex produces an error overfull, and align, linebreak and split don't seem to work.
In my article I have many other long equations.

Code: Select all

\begin{equation}
\delta\Lambda \left( \dot{u}, u'', u' \right) = \frac{\partial}{\partial t} \left( \frac{\partial\Lambda}{\partial \dot {u}} \delta u \right)
- \frac{\partial}{\partial t} \left( \frac{\partial\Lambda}{\partial \dot{u}} \right) \delta u
+ \frac{\partial}{\partial x} \left( \frac{\partial\Lambda}{\partial u''} \delta u' \right) 
- \frac{\partial}{\partial x} \left( \frac{\partial}{\partial x}\left(\frac{\partial \Lambda}{\partial u''} \right) \delta u \right)
+ \frac{\partial^{2}}{\partial x^{2}} \left( \frac{\partial\Lambda}{\partial u''} \right) \delta u
+ \frac{\partial}{\partial t} \left(\frac{\partial \Lambda}{\partial u'} \delta u \right)
- \frac{\partial}{\partial t} \left(\frac {\partial \Lambda}{\partial u'} \right) \delta u
\end{equation}

The LaTeX program you are using gives you a warning and not an error.

Examples of the environments you have already listed and others can be found in the user's guide of the required amsmath package.

Your incomplete example doesn't reveal any of your solution approaches. It'd be appreciated if you show us what you have tried so far.
