Here's an example :
sage: f(x) = -2*x^2+x+3
....: g(x) = -2*(x-1/4)^2+25/8
....: g(x)
-1/8*(4*x - 1)^2 + 25/8
sage:
but I want to keep the form `-2*(x-1/4)^2+25/8` to write it in latex.
I tried `hold` and `with hold:` and also some code with `.mul(` or `.add(` but I have a problem with the power.
My purpose is to do random exercises around quadratic equations, and I started writing this :
from random import sample
def signe():
signe = sample([Integer(i) for i in range(-1, 2, 1) if i != 0],1)
return(signe[0])
def calcul(amax, bmax, cmax):
a = randint(1,amax)*signe()
b = randint(0,bmax)*signe()
c = randint(0,cmax)*signe()
f(x) = a*x^2+b*x+c
alpha = -b/2/a
beta = f(x=alpha)
fcanonique(x) = a*(x-alpha)^2+beta
Delta = b**2-4*a*c
output = r"Soit $f$ le trinôme défini sur $\R$ par ~${}=0$.".format(latex(f(x)))
output += r"\medbreak"
output += r"\begin{enumerate}"
output += r"\item Déterminer une forme canonique de $f$."
output += r"\item Résoudre dans $\R$ l'équation $f(x)=0$ par la méthode de votre choix."
output += r"\item $f$ est-elle factorisable ? Si oui, déterminer en une forme factorisée."
output += r"\item Résoudre dans $\R$ l'équation $f(x)={}$.".format(c)
output += r"\item Résoudre dans $\R$ l'équation $f(x)={}$.".format(beta)
output += r"\end{enumerate}"
output += r"\medbreak\uline{Réponses} :\medbreak"
output += r"\begin{enumerate}"
output +=r"\item On a $f(x)={}$".format(latex(fcanonique(x)))
if Delta < 0:
output += r"\item On reconnaît une équation du second degré de discriminant $\Delta={}<0$, et donc cette équation n'a pas de solution réelle :".format(latex(Delta))
output += "\\bigbreak{}"
output += r"Ce trinôme admet une forme canonique : "
elif Delta == 0:
output += r"\item On reconnaît une équation du second degré de discriminant $\Delta={}$, et donc cette équation admet une unique solution $x_0={}$".format(latex(Delta), latex(alpha))
else:
x1 = simplify((-b-Delta^(1/2))/(2*a))
x2 = simplify((-b+Delta^(1/2))/(2*a))
ffactorisee(x) = a*(x-x1)*(x-x2)
output += r"\item On reconnaît une équation du second degré de discriminant $\Delta={}>0$, et donc cette équation admet deux solutions réelles $x_1$ et $x_2$ avec : \quad $\displaystyle x_1={}$ \quad et \quad $\displaystyle x_2={}$.".format(latex(Delta), latex(x1), latex(x2))
output += "\\bigbreak{}"
output += r"\end{enumerate}"
return(output)
and for example, `calcul(5, 5, 5)` return :
"Soit $f$ le trinôme défini sur $\\R$ par ~$-x^{2} + 4 \\, x - 2=0$.\\medbreak\\begin{enumerate}\\item Déterminer une forme canonique de $f$.\\item Résoudre dans $\\R$ l'équation $f(x)=0$ par la méthode de votre choix.\\item $f$ est-elle factorisable ? Si oui, déterminer en une forme factorisée.\\item Résoudre dans $\\R$ l'équation $f(x)=-2$.\\item Résoudre dans $\\R$ l'équation $f(x)=2$.\\end{enumerate}\\medbreak\\uline{Réponses} :\\medbreak\\begin{enumerate}\\item On a $f(x)=-x + 4$\\item On reconnaît une équation du second degré de discriminant $\\Delta=8>0$, et donc cette équation admet deux solutions réelles $x_1$ et $x_2$ avec : \\quad $\\displaystyle x_1=\\sqrt{2} + 2$ \\quad et \\quad $\\displaystyle x_2=-\\sqrt{2} + 2$.\\bigbreak{}\\end{enumerate}"
Before `if Delta < 0:` I would like `output +=r"\item On a $f(x)={}$".format(latex(fcanonique(x)))` to display the formula without transformation.
Thanks.ryssTue, 19 Jul 2022 20:53:44 +0200https://ask.sagemath.org/question/63309/Displaying and typesetting partitionshttps://ask.sagemath.org/question/62961/displaying-and-typesetting-partitions/ A partition can be viewed as a list or pretty-printed using ascii art. This works fine for me.
A partition can also be LaTeX-ed:
latex(Partition([2,2]))
produces
{\def\lr#1{\multicolumn{1}{|@{\hspace{.6ex}}c@{\hspace{.6ex}}|}{\raisebox{-.3ex}{$#1$}}}
\raisebox{-.6ex}{$\begin{array}[b]{*{2}c}\cline{1-2}
\lr{\phantom{x}}&\lr{\phantom{x}}\\\cline{1-2}
\lr{\phantom{x}}&\lr{\phantom{x}}\\\cline{1-2}
\end{array}$}
}
which typesets fine when inserted into a LaTeX document.
However:
1. When sagetex uses this, and produce the exakt same LaTex snippet, there are TeX errors (which does not stop the document from being typeset, but which are annoying):
(./part.sagetex.sout
./part.sagetex.sout:9: Illegal parameter number in definition of \r@@sageinline0.
2. The LaTex form of the partition does not render well with MathJax, so it is not displayed properly in a Jupyter notebook. I belive that the \cline is the culprit.
I hacked the LaTex output and got something which works well with sagetex, but since it uses the external package ytableu.sty, it does not work with MathJax.
if Partitions.options.convention == "English":
Partitions.options(latex=lambda mu: '\\ydiagram{%s}' % ','.join('%s'%m for m in mu._list))
Here is a kludge for skewpartitions:
def LatexSkew(S):
L = S._list[0]._list
M = S._list[1]._list
ut = '\\ydiagram{'
ut += ','.join([str(b) + '+' + str(a-b) for a,b in zip(L,M)] )
if len(L) > len(M):
ut += ',' + ','.join([str(a) for a in L[len(M):]] )
ut += '}'
return ut
if Partitions.options.convention == "English":
SkewPartitions.options(latex=LatexSkew)
So, at long last the question: how do you professionals typeset and display partitions?
JTSWed, 22 Jun 2022 20:25:29 +0200https://ask.sagemath.org/question/62961/sagetex in Lyx on Mac: Can't compile using latex(pdflatex)https://ask.sagemath.org/question/62888/sagetex-in-lyx-on-mac-cant-compile-using-latexpdflatex/I am trying to use Sagetex within Lyx (Version 2.3) on an M1 Mac (MacOS Monterey 12.4).
Sagetex works fine when I use Aquamacs or TexStudio. Within Lyx, I have installed the sage module available here (https://wiki.lyx.org/Layouts/Modules#toc8) by copying it to "/Applications/LyX.app/Contents/Resources" and clicking "reconfigure". The module is visible under Documents->Settings.
When I activate the sage module within the example.lyx document provided under the URL above, the preview and update icons in the editor are deactivated. Also, under the menu "File->Export", the option "Export [PDF (pdflatex)]" is grayed out. If I choose "Export as..." and subsequently choose PDF(pdflatex), I get the error message "No information for exporting the format LaTeX (pdflatex)". The same happens when I choose export as latex(pdflatex). (BTW It makes no difference whether I add "\usepackage{sagetex}" to the preamble or not.) The only available export option is LyXHTML.
Does anyone have experience with this? Thanks for your help!
cav24Mon, 20 Jun 2022 11:00:56 +0200https://ask.sagemath.org/question/62888/How to break long line of code in sageblock environment (SageTeX)https://ask.sagemath.org/question/59202/how-to-break-long-line-of-code-in-sageblock-environment-sagetex/ So I have long codes written in `sageblock` which I would like to know if it's possible to implement line wraps? It seems the [the docs](http://mirrors.ibiblio.org/CTAN/macros/latex/contrib/sagetex/sagetex.pdf#section.6) suggests SageTeX is using `listings` which I thought according to [this TeX SE answer](https://tex.stackexchange.com/questions/116534/lstlisting-line-wrapping) I could set `breaklines=true` but still it doesn't work.
Do anyone know how to solve it?andrewygThu, 30 Sep 2021 14:26:10 +0200https://ask.sagemath.org/question/59202/siunitx ver 3https://ask.sagemath.org/question/57977/siunitx-ver-3/With the new version of the **LaTex siunitx** package (h**s://ctan.org/pkg/siunitx) the \SI command changed so my:
\newcommand{\sageSIu}[2][]{\sagestr{’\SI[#1]{’+str(#2.value)+’}{’+str(#2.unit)+’}’}}
that prints a quantity from **PhysicalQuantities** (h**s://physicalquantities.readthedocs.io/) is broken.
How can I change the command for:
1. old tex files compabilitie (I think \usepackage{siunitx}[=v2] will work)
2. new tex files
Thanx (many, many)qgfreireMon, 12 Jul 2021 19:51:41 +0200https://ask.sagemath.org/question/57977/How do you assign (different) LaTex names to elements of a list?https://ask.sagemath.org/question/57589/how-do-you-assign-different-latex-names-to-elements-of-a-list/Say I have the following list of variables.
v = {(i,j): var("v_{}{}".format(i, j), latex_name="v_{{}{}}") for i in range(2) for j in range(2)}
How do I make it so that when I use the
show(v[0,0])
command, I get $v_{0,0}$ as output? I've tried stuff like
v = {(i,j): var("v_{}{}".format(i, j), latex_name="v_{i,j}") for i in range(2) for j in range(2)}
and
v = {(i,j): var("v_{}{}".format(i, j), latex_name="v_{{i}{j}}") for i in range(2) for j in range(2)}
but it only ever give me stuff like $v_{i,j}$ where it's just the literal symbols $i$ and $j$, not the entries of
v[k,m]
for some $k$ and $m$ I plug in, like 0, 0.
sum8tionWed, 16 Jun 2021 21:52:17 +0200https://ask.sagemath.org/question/57589/Problems with sagetexhttps://ask.sagemath.org/question/51945/problems-with-sagetex/Texmaker does not give me the required PDF file although in Sage it is written:
Sage processing complete. Run LaTeX on st_example.tex again.
1. I took the example at https://doc.sagemath.org/html/en/tutorial/sagetex.html, pasted this code into Texmaker and saved it under the file name `st_example.tex`.
At this link http://www.cecm.sfu.ca/sage/spkg/upstream/sagetex/index.html I chose `sagetex-3.3.tar.gz`.
I put `st_example.tex` into the file `sagetex3.3`. There I compiled it using pdflatex.
After this a new file appeared, `st_example.sagetex`.
2. I uploaded `st_example.sagetex` on [CoCalc](https://cocalc.com). Then another code appeared, I clicked on Terminal wherein I wrote sage `st_example.sagetex.sage`. After this there was written:
Sage processing complete. Run LaTeX on st_example.tex again.
Especially new files appeared e.g st_example.sagetex.sout.
3. After again compiling `st_example.tex` in LaTeX with pdflatex there were still these question marks and nothing changed.
This is the source file:
\documentclass{article}
\usepackage{sagetex}
\begin{document}
Using Sage\TeX, one can use Sage to compute things and put them into
your \LaTeX{} document. For example, there are
$\sage{number_of_partitions(1269)}$ integer partitions of $1269$.
You don't need to compute the number yourself, or even cut and paste
it from somewhere.
Here's some Sage code:
\begin{sageblock}
f(x) = exp(x) * sin(2*x)
\end{sageblock}
The second derivative of $f$ is
\[
\frac{\mathrm{d}^{2}}{\mathrm{d}x^{2}} \sage{f(x)} =
\sage{diff(f, x, 2)(x)}.
\]
Here's a plot of $f$ from $-1$ to $1$:
\sageplot{plot(f, -1, 1)}
\end{document}

For example, consider `v = vector([1, 2, 3])`. In sagetex, the command `$v=\sage{v}$` renders as
$$
v=(1, 2, 3)
$$
Instead, I want my vectors to take the form
$$
v=\left[\begin{array}{rrr}1&2&3\end{array}\right]^\intercal
$$
I thought I could do this by resetting the `_latex_` method of the `sage.modules.free_module_element.FreeModuleElement` class as follows.
def my_vector_latex(self):
return matrix(v)._latex_() + r'^\intercal'
setattr(sage.modules.free_module_element.FreeModuleElement, '_latex_', my_vector_latex)
However, this code throws the following error:
TypeError: can't set attributes of built-in/extension type 'sage.modules.free_module_element.FreeModuleElement'
So, it looks like I can't modify the methods of `FreeModuleElement` in this way. Is there anything else I could do?more_weightTue, 13 Oct 2020 19:37:51 +0200https://ask.sagemath.org/question/53892/Can sagetex generate tex files?https://ask.sagemath.org/question/53227/can-sagetex-generate-tex-files/I'm writing a latex document that will eventually need to be compiled on a machine that does not have sage on it.

Using Sage\TeX, one can use Sage to compute things and put them into your \LaTeX{} document. For example, there are

You don't need to compute the number yourself, or even cut and paste it from somewhere.
Here's some Sage code:

Can you help with these things:
- On macOS 10.14.6, I downloaded and installed
`sage-9.1-OSX_10.11.6-X86_64.app.dmg` from the
[SageMath download mirror at MIT](https://mirrors.mit.edu/sage/osx/intel/index.html).
But although the app starts the way the page says, "like most other
Mac applications," the interface is quite different from most other
Mac applications. Instead of the usual sequence,
"**AppName**, **File**, **Edit**, **View**, ... **Window**, **Help**,"
Sage has "**Sage**, **File**, **Server**, **Terminal Session**, **Development**, **Help**."
I recognize "**Sage**," "**File**," and "**Help**," but not the rest.
Is there introductory documentation or a tutorial somewhere
that explains how to use Sage from this interface?
- Regarding the installation itself, the
[SageMath components documentation](https://www.sagemath.org/links-components.html)
lists 84 separate components. Some of these, like R and Python,
I already have installed and use regularly in different contexts.
Does SageMath install duplicates, or does it use the already installed
versions? And in either case, how does SageMath handle component
updates and possible incompatibilities associated with them?
- I want to use SageMath with [LyX](https://www.lyx.org/)
and therefore need SageTeX. In the SageMath documentation, the
[SageTeX tutorial](https://doc.sagemath.org/html/en/tutorial/sagetex.html#sec-sagetex-install)
says SageMath comes with SageTeX, and all one needs to do
is to make TeX aware of it. But the page refers to `SAGE_ROOT`,
and since I installed using the `.dmg` file, I'm not really sure
where `SAGE_ROOT` is. How does one find it?GnossosFri, 31 Jul 2020 18:07:54 +0200https://ask.sagemath.org/question/52776/Problems with SageTex on MacOShttps://ask.sagemath.org/question/52612/problems-with-sagetex-on-macos/I have follow the instructions according with the sage tutorial guide for install SageTex and for "LaTex to know Sage", to being able to use SageTex on MacOS, but although it's recognize the sage.sty file when I compile a document on each part of sage it displays "??", I have no more ideas what to do, I have use a lot of differents versions of Sage but no one works.emaspWed, 22 Jul 2020 09:01:02 +0200https://ask.sagemath.org/question/52612/How allow renaming SageMath-x.y.app to SageMath.app for sagetexhttps://ask.sagemath.org/question/51969/how-allow-renaming-sagemath-xyapp-to-sagemathapp-for-sagetex/When using the `sagetex` with LaTeX under MacTeX and the TeXShop front end, the suggested method (from the TeXShop docs) is to rename `SageMath-x.y.app` to just `SageMath.app` and then to create symlinks for the executable `sage` and for `sagetex.sty` within the Contents of the app.
That works just fine to use `sagetex` in LaTeX.
However, once the renaming is done, the app itself no longer works! Once I open the renamed SageMath.app, I get a pop-up error message "Juypyter Server failed to start...", and inspecting the log reveals:
/Applications/SageMath.app/Contents/Resources/sage/src/bin/sage: line 617: /Applications/SageMath-9.1.app/Contents/Resources/sage/local/bin/python3: No such file or directory
/Applications/SageMath.app/Contents/Resources/sage/src/bin/sage: line 617: exec: /Applications/SageMath-9.1.app/Contents/Resources/sage/local/bin/python3: cannot execute: No such file or directory
Apparently access to `python3` has been hard-coded into the `sage` executable so that it is expect to be in the file tree with root the original name `SageMath-x.y`.
Is there some workaround so that one can both use `sagetex` in the way recommended by the MacTeX/TeXShop world and still be able to use the SageMath app normally to start the Jupyter server, etc.?murrayeSun, 14 Jun 2020 16:51:53 +0200https://ask.sagemath.org/question/51969/How do I get the output of this text in latex with sagetex?https://ask.sagemath.org/question/51919/how-do-i-get-the-output-of-this-text-in-latex-with-sagetex/Using Sage\TeX, one can use Sage to compute things and put them into

The relevant part is around line 63 of `sagetex.py`, which I quote here.

```python

lines = s.splitlines()

As in this quotation, I just inserted the letter 'r' to the left of the string on line 63.
It is the first line of the deepest indentation in this quotation.
Is this a good solution?

Reading the PythonTex documentation this problem doesn't exist.
Starting with the answer /#49745
\begin{sagesilent}
def SIsage(number,units=0):
if units==0:
if number in ZZ or number.parent()==QQ:
return r"\SI{"+ str(number) + "}"
else:

\sagestr{SIsage(2442,"\kilo\metre\squared")}
\sagestr{SIsage(2442)}
and it works except when using `\newton` witch it become "ewton" problably cause to `\n`
After this I want to create a new custom LaTeX command that replace `\SI{}{}` but I have some trouble with non-default arguments. I didn't understand how them work. I want be able to use both of `\SI{number}{units}` that `\SI{number}` without units. Probably the best choise is to create two different commands(?)
\newcommand{\SIsage_units}[1]{,"#1"}
\newcommand{\SIsage_number}[1]{\sagestr{SIsage(#1}}
\newcommand{\SISAGE}[2]{\SIsage_number{#2}\SIsage_units{#1})} #doesn't work
The command I want:
\SISAGE{21}{\kilo\metre\squared}
\SISAGE{26}{}
So my problems are:
1. how to avoid `\n`
2. how to set an unic custom command `\SISAGE`
Thanks everybodysononicolaFri, 07 Feb 2020 07:26:49 +0100https://ask.sagemath.org/question/49836/Spanish numbers using LaTeXhttps://ask.sagemath.org/question/47018/spanish-numbers-using-latex/Dear SageMath community,
I am currently writing a LaTeX document in Spanish that relies heavily on sageTeX for computations. The rules for writing numbers in Spanish are a little different from English ones. For example, we are prohibited from using commas to separate every 1000 factor, instead using a small space, only if the number is longer than four digits; otherwise, no sign should be used. On the other hand, the decimal point is actually a decimal comma. For example,
- 1,000,000.25 should be written as 1 000 000,25
- 123,456,789.123456789 should be written as 123 456 789,123 456 789
- 4,000 should be written as 4000
Using sageTeX, SageMath's `latex` command, and LaTeX babel package, it is easy to replace the decimal point with a decimal comma. It is also easy to eliminate the commas for every 1000 factor. However, I haven't been able to put a small space instead.
I could use the `siunitx` LaTeX package, which has a command, `\num`, that does exactly this processing. However, it doesn't work with sageTeX's `\sage` command or any of it's environments. The only solution I can find is to apply the `\num` command directly to every number generated by SageMath via the `latex` command.
My problem is: I don't know how to do this, specially in cases where numbers are entries of a matrix, or the coefficients of a polynomial. So, **how could I apply the `\num` command to every number independently using the `latex` command?**
Thanks in advance for your answers! Any alternative approach is also welcomed.dsejasSun, 30 Jun 2019 06:08:29 +0200https://ask.sagemath.org/question/47018/SageTeX: sagecommandline problemhttps://ask.sagemath.org/question/49724/sagetex-sagecommandline-problem/As a simple example of the problem I have encountered

I'm new to SageMath and just installed it. Unfortunately I'm not too concerned with the importance of the information you might need to help me out - sorry for that.
So I have Windows 10 and I installed SageMath via These pre- built binaries if that's what it is called. I used the sagetex package to create a .sage file and I tried to run it with sage obviously. Therefore, I opened the Shell and typed
sage 'C:/Users/scheu/OneDrive/Desktop/sagetex.sage'
with sagetex.sage being my .sage file and I'm getting the following:

First of all, I need to Mention that I am completely new to Sage Math and I have no idea what causes my problem(s), like seriousely, no idea.
When I start SageMath, it instantly crashes, I don't even touch anything. I'm running Windows 10 and I downloaded the binaries, a virtual box and this sage-8.6.tar.gz file. I am sure that I must be missing something but I don't know what.
Yesterday, I managed to get Sage to work, so in the terminal i could write simple commands like
sage:4+3
and later, I reinstalled python. Now it does not work anymore. My original aim was it to have sagetex in Latex, but for some reason running the .sage file which is created with every document using sagetex doesn't do anything and sage does not compile my document. And yes, I did follow the instructions how to make sagetex known to tex.
I have no idea how to continue, so many problems and i'm desperately trying to get things to work. (Feel like I downloaded half the Internet...)

I've been writing a book with the help of SageTeX. Until yesterday, I was working with SageMath v8.6, and everything work perfectly. Today I downloaded SageMath v8.7 binary for Linux, and replaced the corresponding SageTeX files. But when I tried to compile the book, suddenly I receive an error message:
> Traceback (most recent call last):
>
> File "book.sagetex.sage.py", line 5158, in <module>

> `_st_.endofdoc()`

>
> m.update(bytearray(line,'utf8'))
>
> UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 29: ordinal not in range(128)
The only difference from yesterday is the new version of SageMath. Can somebody explain/help me with this matter?
Thanks in advance for your answers!dsejasTue, 02 Apr 2019 13:03:58 +0200https://ask.sagemath.org/question/45985/
