I'm using LyX all the time and over the last 2 years I've accumulated some very handy macros for my lecture notes. As it is today, every time I start a new document, I copy and paste the macros from one of my other documents. Is it possible, somehow, to automatically load macros for all files? (...

It works if you make sure that scriptsize math is set up before listings starts: \documentclass{article} \usepackage{unicode-math} \usepackage{listings} \lstset{basicstyle=\scriptsize} \begin{document} \sbox0{\scriptsize $x$} \lstinputlisting{test.cpp} \end{document}

In schema diagram one attribute(foreign key) points another attribute of different table. I can point table to table, but not attribute to attribute. You just modify my following MWE that give the following result. One arrow from dept_name of instructor to dept_name of department. MWE(tak...

Starting from the question, how do I find a bundle of parallel planes (equipotential surfaces) of the type $$\mathcal{F}: ax + by + cz + k = 0 $$ with $ k\in \mathbb{R}$, orthogonal to the uniform electric field starting from the equation $\overline E=-\overline \nabla V$? The problem can be con...

We known that the potential generated by a charge pointwise $q$ is $V(r) = kq/r $ and the equipotential surfaces (in 3D) are spheres centered in the charge with $r\geq 0$ where $r=d(O,P)$, i.e. the distance between the origin and a generic point $P$. In fact if we are in space, where an orthono...

I'll be travelling from Europe to Brazil (Rio). I would like to use this opportunity and see the Water Plant of Itaipu and the Waterfalls of Iguazú as a part of this visit. Now, if it were in Europe or the US, I would fly to the nearest airport (in this case it's IGU) early in the morning, rent ...
