In my Sage/CoCalc article (Sage has recently merged with CoCalc), I am unable to create an Array without a red issue bar popping up. Morover, I am unable to cross out element in my array. The issue(s) is `PackageArrayError; illegal pream-token (1): PackageArrayError; illegal pream-token (2)`: ...... and so on.

\title{Regarding Your Version of Natural Density to Rationals}
\author{Aiyappan Nair}
\begin{document}
\maketitle
Your version of asymptotic density to rationals differs from my own version. It is not a simplification but rather a change in definition. And although it is much more simple there are flaws that I would like to mention.
\subsection{Counter-Example}
As mentioned earlier, if sets $T_1,T_2,T_p$ are subsets of $\mathbb{Q}$, a density $D$ should have the following qualities.
(1) If $T_1=T_2$ then $D(T_1)=D(T_2)$
(2) If $T_1\subset{T_2}$ then $D(T_1)\le D(T_2)$
In your new version of the density
$$D=\lim_{r\to\infty}\frac{\left|T_1\cap V(r)\right|}{|V(r)|}$$
Where
$$V(r)=\left\{\left.\frac{m}{n}\right|1<m<r,1<n<r,\gcd(m,n)=1\right\}$$
and $m,n,r\in\mathbb{Z}$
If we set $T_1=\left\{\left.\frac{m}{2n+1}\right|m,n\in\mathbb{Z}\right\}$ and $T_2=\left\{\left.\frac{m}{4n+2}\right|m,n\in\mathbb{Z}\right\}$, I found that $D(T_1)>D(T_2)$ even though $T_1\subset T_2$. Which breaks requirment (2).
\subsection{Proof of Counter Example}
Imagine $V(r)$ as an array of values, restricted by $r$. The numerator is from listed as columns each labelled from $[1,r]$ and the denominator is listed as row labelled from $[1,r]$.
\begin{array}{|l|col1 col2 col3 col4 col5 col6 col7 col8}
& 1 & 2 & 3 & 4 & 5 & .. & r\\
\hline
1 & 1/1 & 2/1 & 3/1 & 4/1 & 5/1 & ..& r/1\\
2 & 1/2 & \st{2/2} & 3/2 & 4/2 & 5/2 & ..& r/2\\
3 & 1/3 & 2/3 & 3/3 & 4/3 & 5/3 & ..& r/3\\
4 & 1/4 & 2/4 & 3/4 & 4/4 & 5/4 & ..& r/4\\
5 & 1/5 & 2/5 & 3/5 & 4/5 & 5/5 & ..& r/5\\

it should be

I am visualizing 3D curves from data points via line3d() and than using the show() method on the graphics objects. line3d? and show? give a short list of arguments such as color, thickness, radius for line3d, and frame for show. I know there are many more arguments, for example corner_cutoff for smoothing, but I only stumble upon them while browsing the Sage documentation. So far, I haven't found a source to list all the arguments for line3d or similar functions. I understand that these are Python wrappers and I tried things like dir() but I could not find more information than that given by line3d? Where am I going wrong? I am quite sure there are arguments controlling background color, the way frames and axes are labeled, etc. How can I find them? -Thanks.ikolMon, 26 Jan 2015 19:39:20 -0600http://ask.sagemath.org/question/25609/Unable to build documentation (ValueError: unknown locale: UTF-8)http://ask.sagemath.org/question/25089/unable-to-build-documentation-valueerror-unknown-locale-utf-8/ When I try to build the sage documentation I get an error.

I would like to have it alphabetically mixed caps in my file. How can I achieve this?
(It appears there is a Sphinx config option named autodoc_member_order that changes it for the whole project but maybe I'm missing something that was added by Sage)
**Update**: I tried to work around it by naming the lowercase function with initial cap, and making an alias to that but now the function docs are duplicated! Needless to say, I find the limited options in Sphinx very disappointing.rwsThu, 24 Jul 2014 08:59:35 -0500http://ask.sagemath.org/question/23568/the same function appears twice in the documentationhttp://ask.sagemath.org/question/11056/the-same-function-appears-twice-in-the-documentation/The functions base_field()/constant_base_field()/constant_field()/vector_space()/maximal_order()/random_element appear twice in the following document:

MicheleWed, 05 Feb 2014 00:02:57 -0600http://ask.sagemath.org/question/10993/Documentation for show involving ymin and ymaxhttp://ask.sagemath.org/question/10733/documentation-for-show-involving-ymin-and-ymax/I was reading the documentation on 2d plotting again and I noticed something that I find strange. In the [plot documentation](http://www.sagemath.org/doc/reference/plotting/sage/plot/plot.html#sage.plot.plot.plot), there is the following phrase:
>If you want to limit the plot along the horizontal axis in the final rendered figure, then pass the xmin and xmax keywords to the show() method. To limit the plot along the vertical axis, ymin and ymax keywords can be provided to either this plot command or to the show command.
Ok, so this feels pretty obvious and all is well and good. But then you get [other questions](http://ask.sagemath.org/question/1242/add-plots-with-different-ymin-ymax-parameters) that show that ymin and ymax don't behave naively, nor are they associated directly with plot. Instead, that [answer](http://ask.sagemath.org/question/1242/add-plots-with-different-ymin-ymax-parameters?answer=1957#1957) says that ymin and ymax are really just always passed to show, and so should be thought of as show arguments.
Hmm, so it's not so obvious. So we might go to the [show documentation](http://www.sagemath.org/doc/reference/plotting/sage/plot/graphics.html#sage.plot.graphics.Graphics.show) to better understand what is going on. Unfortunately, show does not mention anything about ymin or ymax, or what happens when they're added together.
As far as I can tell, there is nothing in any show documentation that mentions ymin or ymax. Is that correct? If so, is that by design?mixedmathWed, 13 Nov 2013 16:48:47 -0600http://ask.sagemath.org/question/10733/Searching local HTML Docs with Chrome browser doesn't find anything, everhttp://ask.sagemath.org/question/10118/searching-local-html-docs-with-chrome-browser-doesnt-find-anything-ever/Using locally generated documentation ("make doc" in install dir), the Chrome browser search feature doesn't ever find anything.

I guess my general question is: for someone who is still very much a novice to python and sage, how would one go about learning more about specific commands like `%hide`.

I have created a .sage file with functions of my own, and have documented every function following http://www.sagemath.org/doc/developer/conventions.html#documentation-strings
Is there a way of generating automatically a *pdf* or *html* with the docstring of every function in the library, such as the ones in the sage documentation?
Or, more or less the same: can I use something like 'sage -docbuild' for a custom file (with standard doctrings)?

These issues occur many times within one document. To point one out, line 11, page 4 of reference.pdf, there is a line that goes off the page. That particular problem seems to be consistent throughout the document. Is there any fix for this?
Edit: Here is the offending example:
sage: sage.plot.plot.EMBEDDED_MODE = True
sage: trace(print factor(10))
...
NotImplementedError: the trace command is not implemented in the Sage notebook; you must use the
at which point it goes off the page.

One think I am missing here is 'suggestions' or 'related functions' in the helh-file in the MATLAB. For example, suppose one has a list A and he wants to remove first element of it. Now if one looks for a 'remove', he may also be interested in other list related commands like - 'append','clear','add',etc.
Is there any scope of bring this modifications in help-files in near future? hector1618Sat, 11 Sep 2010 08:36:49 -0500http://ask.sagemath.org/question/7654/Can I browse Cython Docs within the notebook()?http://ask.sagemath.org/question/7647/can-i-browse-cython-docs-within-the-notebook/http://pypi.python.org/pypi/bintrees/0.3.0
So I notice this webpage that says that Cython has Red-Black Trees (or someone has used Cython to implement them), and I think "Great! How can I get started using them?!"
Of course, I not knowing whether this package is included in sage (or if it is how to get to it); I type "sage: cython?", and I am now unsure where to look. Are the Cython docs included in Sage? What about other packages? Is it standardized within the notebook somehow? Of the included packages, do they have optionally included sub-packages? Tips? Thanks! When I say "included", I mean "bundled" in the distribution.ccanoncSat, 28 Aug 2010 17:28:17 -0500http://ask.sagemath.org/question/7647/
