This is a list of common code templates and styles we use at specialfunctionswiki.

Theorem/proof box template

The code

<div class="toccolours mw-collapsible mw-collapsed">
<strong>THEOREM/LEMMA/PROPOSITION:</strong> STATEMENT OF THEOREM
<div class="mw-collapsible-content">
<strong>Proof:</strong> proof goes here █ 
</div>
</div>

creates

Images

Put images into galleries. Thumbnails and frames break the theorem/proof box template. The code

<div align="center">
<gallery>
File:Arccos.png|Graph of $\mathrm{arccos}$ on $[-1,1]$.
File:Complex arccos.jpg|[[Domain coloring]] of [[analytic continuation]].
</gallery>
</div>

creates

Mathematica code

Domain colorings

We use the code

ComplexGraph[f_, {xmin_, xmax_}, {ymin_, ymax_}, 
  opts : OptionsPattern[]] := 
 RegionPlot[True, {x, xmin, xmax}, {y, ymin, ymax}, opts, 
  PlotPoints -> 200, ColorFunctionScaling -> False, 
  ColorFunction -> 
   Function[{x, y}, 
    With[{ff = f[x + I y]}, 
     ColorConvert[
      Hue[(2. Pi)^-1 Mod[Arg[ff], 2 Pi], 1, 
       1 - (1.2 + 10 Log[Abs[ff] + 1])^-1], "LAB"]]]]

to generate complex domain colorings. This coloring applied to the identity function $f(z)=z$ with the Mathematica code

 f[z_]:=z
ComplexGraph[f,{-10,10},{-10,10}]

generates the following picture:

Thumbnails

We use the Mathematica code

Plot[AiryAi[x], {x, -12, 3}, PlotStyle -> {Thickness[0.04], Black}, AxesStyle -> Thickness[0.01], Ticks -> None]

to output the image

which we upload to the Wiki with name Airyaithumb.png use a thumbnail in an HTML table cell with the code

<td><center>[[File:Airyaithumb.png|45px|link=Airy Ai]]<br />
[[Airy Ai]]</center></td>

to display it.
