Edit Sorry, I misread the question and thought that you wanted to circle the exponents. Modifying my first solution you can circle the coefficients with: \documentclass{article} \usepackage{amsmath} \usepackage{tikz} \usetikzlibrary{decorations.text} \newcommand{\tikzmark}[2]{% \tikz[remember picture,baseline=-2pt] ...

You have to remove the option overlay from \tikzmark definition first. And second, alter the definition to take the same argument as label and content. Also, if you want circles to have same radius, fix some value for minimum width key. With these it becomes, \newcommand{\mathtikzmark}[1]{\tikz[baseline={(#1.base)},remember picture] \node[draw,circle,inner ...

\twoheadleftarrow and \twoheadrightarrow can be combined to \twoheadleftrightarrow: \documentclass{article} \usepackage{amssymb} \newcommand*{\twoheadleftrightarrow}{% \twoheadleftarrow \mathrel{\mkern-15mu}% \twoheadrightarrow } \begin{document} \[ \twoheadleftrightarrow \scriptstyle \twoheadleftrightarrow \scriptscriptstyle ...

Here's the way, reflecting the arrow: \documentclass{article} \usepackage{amsmath,amssymb,graphicx} \makeatletter \providecommand{\leftsquigarrow}{% \mathrel{\mathpalette\reflect@squig\relax}% } \newcommand{\reflect@squig}[2]{% \reflectbox{$\m@th#1\rightsquigarrow$}% } \makeatother \begin{document} $A\rightsquigarrow B\leftsquigarrow C$ \end{document} ...

It is not amsmathcommand, but one can obtain it through txfonts package: \documentclass{article} %\usepackage{amsmath} \usepackage{txfonts} \begin{document} $\leftsquigarrow$ \end{document}

You could use the tikz package and the arrows and decorations library to achieve something similar to your drawing. \documentclass[tikz]{standalone} \usetikzlibrary{arrows,decorations.pathmorphing} \begin{document} \begin{tikzpicture}[ >=stealth', pos=.8, photon/.style={decorate,decoration={snake,post length=1mm}} ] \draw[gray,thick] (-2,0) -- ...

mathabx also has: As to MnSymbol, it has a whole tribe: MdSymbol has about as many:

In this case you need to use Arrow3 instead of just Arrow. With a simple data file it gives \begin{filecontents*}{data.csv} 0.81,0.59,0.1 0.31,0.95,0.2 -0.31,0.95,0.3 -0.81,0.59,0.4 -1,0,0.5 -0.81,-0.59,0.6 -0.31,-0.95,0.7 0.31,-0.95,0.8 0.81,-0.59,0.9 1,0,1 \end{filecontents*} \documentclass[margin=1cm]{standalone} \usepackage{asymptote} ...

The resolution on your dropbox image is a little low, but I think that you are trying to make something like this: If this is what you want then you can get it using the double option to the \draw command. This draws "double lines" rather than single lines. You can control the distance between the lines using double distance. Here's the full code: ...

This is a starting point. First define a style (LL here) for snake lines. Then draw a line via \draw[options] (x1,y1) --(x2,y2)node[position]{label}; % Euclid coordi \draw[options] (0,0) --(alpha:radius)node[position]{label}; % polar coordi Options: thick, very thick, color, arrow type,...,LL] Code \documentclass[10pt,a4paper]{standalone} ...

I think this is what you mean. I use the pst-poly package; it loads pst-node and pstricks. To change its size, just change the value of unit. The solution is almost as simple as possible. Almost, because there seems to be a small bug in pst-poly – unless I missed something: I have to draw an equilateral triangle with invisible sides, and ...
