Hello everybody,

I would need your help to change the width of my inline todonote...
Indeed, it takes the whole width, and I didn't find any tip in other forums, websites and even in the documentation.

Package needed : todonote

Here's a MWE (a bit long, cause I kept the equations) :

\documentclass[a4paper, 12pt, fleqn]{article}
\usepackage{todonotes}
\usepackage[utf8]{inputenc}
\usepackage{amsmath}
\usepackage[frenchb]{babel}

\usepackage[a4paper]{geometry}
\geometry{top=2cm, bottom=2cm, left=3cm, right=3cm}
\setlength{\marginparwidth}{2.5cm}

\begin{document}

\begin{tabular}{rcl}
$f\left(x + 2\pi\right)$&=&$ \dfrac {3\cos^2\left(x + 2\pi\right)+1}{\cos^3\left(x + 2\pi\right)+1}$\\\\
        &$=$& $\dfrac {3\times \cos\left(x + 2\pi\right)\times \cos\left(x + 2\pi\right)+1}{\cos\left(x + 2\pi\right)\times \cos\left(x + 2\pi\right)\times \cos\left(x + 2\pi\right)+1}$ \\\\
        && \todo[inline]{Car $\cos\left(x + 2\pi\right)=\cos\left(x\right)$} \\
        &$=$& $\dfrac {3\times \cos\left(x\right)\times \cos\left(x\right)+1}{\cos\left(x\right)\times \cos\left(x\right)\times \cos\left(x\right)+1}$\\\\
        &$=$& $\dfrac {3\cos^2\left(x\right)+1}{\cos^3\left(x\right)+1}$
\end{tabular}\\

\noindent
Donc, $\forall x\in D, f\left(x+2\pi\right)=f\left(x\right)$\\
$f$ est donc $2\pi$ périodique.


\end{document} 

Thanks for your future help!

I am in a bit of a hurry... Pleaseee...

[Pierrotdu18]

Hmm.... In the doc, it is said that "The width of inline todonotes will always be the same as the current line width."...
So, would you have an idea?...

Why do you use a table for the math environment?

To change the linewidth for your inline todonote put it in a \parbox.

\documentclass[a4paper, 12pt, fleqn]{article}
\usepackage{todonotes}
\usepackage[utf8]{inputenc}
\usepackage{amsmath}
\usepackage[frenchb]{babel}

\usepackage[a4paper]{geometry}
\geometry{top=2cm, bottom=2cm, left=3cm, right=3cm}
\setlength{\marginparwidth}{2.5cm}

\usepackage{amsmath}

\begin{document}

\begin{align*}
f\left(x + 2\pi\right)&= \dfrac {3\cos^2\left(x + 2\pi\right)+1}{\cos^3\left(x + 2\pi\right)+1}\\
        &=\dfrac {3\times \cos\left(x + 2\pi\right)\times \cos\left(x + 2\pi\right)+1}{\cos\left(x + 2\pi\right)\times \cos\left(x + 2\pi\right)\times \cos\left(x + 2\pi\right)+1} \\
        &\quad\,\text{\parbox{0.4\linewidth}{\todo[inline]{Car $\cos\left(x + 2\pi\right)=\cos\left(x\right)$}}}\\
        &=\dfrac {3\times \cos\left(x\right)\times \cos\left(x\right)+1}{\cos\left(x\right)\times \cos\left(x\right)\times \cos\left(x\right)+1}\\
        &=\dfrac {3\cos^2\left(x\right)+1}{\cos^3\left(x\right)+1}
\end{align*}

\noindent
Donc, $\forall x\in D, f\left(x+2\pi\right)=f\left(x\right)$\\
$f$ est donc $2\pi$ périodique.

\end{document}

Thank you, it works
But I found another way to create a non-inline todonote

Are you willing to share this other method with us? Might be handy some time.
