I would really like to see the full .tex file we're talking about.

I'll give it a try tomorrow.. Thanks in advance

edit: I gave it a try today. Looks a lot better, I like the layout very much. Thank you

Hello fellow LaTeX users.

I have a problem with a long line in an align-environment. The code looks as follows:
\begin{align}
h'(x)&=\lim_{\Delta x\to 0}\frac{h(x+\Delta x)-h(x)}{\Delta x}\Leftrightarrow\\
h'(x)&=\lim_{\Delta x\to 0}\frac{f(x+\Delta x)\cdot g(x+\Delta x)-f(x)\cdot g(x)}{\Delta x ...
