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!
