# Add an equation at the bottom of a two-column conference paper

The following related problem is what I am looking for but still cannot solve my question:

I am using a two-columns conference paper template, and I want to put the equation at the bottom of page.

\documentclass[conference]{IEEEtran}
\usepackage{blindtext, graphicx}
\usepackage{amsmath}
\usepackage[tc]{titlepic}
\usepackage{amssymb}
\usepackage{amsfonts}
\usepackage{lipsum}
\usepackage{float}
\usepackage{cuted}
\usepackage{amsthm}
\newtheoremstyle{case}{}{}{}{}{}{:}{ }{}

\begin{document}

\begin{strip}
\begin{aligned} R = \begin{bmatrix} c\theta+n_1^2(1-c\theta) & n_1n_2(1-c\theta) -n_3s\theta & n_1n_3(1-c\theta)+n_2s\theta \\n_2n_1(1-c\theta)+n_3s\theta & c\theta+n_2^2(1-c\theta) & n_2n_3(1-c\theta)-n_1s\theta \\n_3n_1 (1-c\theta)-n_2s\theta & n_3n_2(1-c\theta)+n_1s\theta & c\theta+n_3^2 (1-c\theta) \end{bmatrix}. \end{aligned}
\end{strip}

\end{document}


However, this equation shows up in the middle of that page. I want to put it at the bottom not the middle of page.

How to fix it?

• Your code shows only the equation. How do you want we can test what's happening? Dec 24, 2016 at 2:19
• @Bernard I have no idea how to put my whole article here, which is too long. Could anyone please just show me how to do it? Or you could put arbitrary contents besides the equation. Dec 24, 2016 at 2:24

• Just put the preamble and some text with the lipsum package, for instance, so as to reproduce your problem. Dec 24, 2016 at 2:29

try to enclose your equation in \begin{figure*} ... \end{figure*}. with use of package stfloats it can be set on bottom of page:

\documentclass[conference]{IEEEtran}
\usepackage{blindtext, graphicx}
\usepackage{amsmath}
\usepackage[tc]{titlepic}
\usepackage{amssymb}
\usepackage{amsfonts}
\usepackage{lipsum}
\usepackage{float}
\usepackage{cuted}
\usepackage{amsthm}
\newtheoremstyle{case}{}{}{}{}{}{:}{ }{}

\usepackage{showframe}% <-- only for show page layout, in real document had to be deleted
\renewcommand*\ShowFrameColor{\color{red}}

\begin{document}
\lipsum[1]
$$2+2=4$$
\lipsum[2]
\begin{figure*}[b]
\begin{aligned} R = \begin{bmatrix} c\theta+n_1^2(1-c\theta) & n_1n_2(1-c\theta)-n_3s\theta & n_1n_3(1-c\theta)+n_2s\theta \\ n_2n_1(1-c\theta)+n_3s\theta & c\theta+n_2^2(1-c\theta) & n_2n_3(1-c\theta)-n_1s\theta \\ n_3n_1 (1-c\theta)-n_2s\theta & n_3n_2(1-c\theta)+n_1s\theta & c\theta+n_3^2(1-c\theta) \end{bmatrix}. \end{aligned}
\end{figure*}
\lipsum[3-9]
\end{document}

• Thanks. Just one question: what is \lipsum[2], \lipsum[3-9], what do they mean? Dec 24, 2016 at 2:38
• \lipsum generate dummy text, with option [2] is selected second paragraph in this text, with [3-9] paragraphs from 3 to 9. With this paragraphs are simulated real text (which is not known to us). Dec 24, 2016 at 2:52
