I am trying to make my first LaTeX file and have been reading syntax for a bit and have not been able to figure one thing out yet and don't seem to find anything about it online so I thought I might just ask:)

How is it possible to place an image next to an equation?

I tried to do it by wrapping it around, putting it into a table or anything similar but I can't get it working... Of course I could just have used the syntax wrong since I'm new to the subject:) It's for a summary for my exams and the pages are limited so I would like to save some space, plus it would look a lot better.

Additionally, if anyone could give me a link to a tutorial that is a bit more extensive than just the basics i would be very thankful as well!

\documentclass[11pt, a4paper]{article}      
\geometry{left=5mm, right=5mm, top=0mm, bottom=5mm}

\title{\huge {\textbf{Lineare Algebra}}}

Das Skalarprodukt ergibt die L\"{a}nge der Projektion von \ensuremath{\vec{a}} auf \ensuremath{\vec{b}}.

\begin {tabular}{p{10cm}l}
{\begin {align*}
\vec{a} \bullet \vec{b}& = |\vec{a}| \cdot |\vec{b}| \cdot \cos(\phi) \\
                       & = a_x  \cdot b_x + a_y \cdot b_y + a_z \cdot b_z \\
            \cos(\phi) & =  \frac {\vec{a} \bullet \vec{b}}{|\vec{a}| \cdot  |\vec{b}|}\\
                       & = \frac {a_x  \cdot b_x + a_y \cdot b_y + a_z \cdot b_z}{\sqrt{a_x^2 + a_y2 + a_z^2}\sqrt{b_x^2 + b_y^2 + b_z^2}}
\end {align*}}

This is the outcome now


There are several possibilities. Perhaps the simplest is




or with align:





  • thank you for your answer, i tried to do that before but it did not seem to work because it seemed to have a problem with the equation, would it be possible that the the align-environment doesn't work with tabular? – David Wright Aug 4 '12 at 12:14
  • 1
    should work but you need extra brace group to hide the &, did you make sure to use a p column for the display environments (which won't work in a c columns) But this is why we always ask people to include a complete document in their question if you'd included align I would have used it in the answer – David Carlisle Aug 4 '12 at 12:25
  • Thanks I just realised that so I updated the question and pasted the part of the document! But I don't understand what you meant with p and c columns to be honest..:) – David Wright Aug 4 '12 at 12:33
  • equation and align are display enviornments that need to go in vertical material, so they work in a \parbox but not in an \mbox which is a single-line construct. In a table l c r are single line horizontal boxes like \mbox so you need a p columns of a specified width which makes a paragraph box to hold the display. Your updated question used ll change that to p{something}l would have been enough for equation but for align the & confuses things so you need an extra {} as in my answer – David Carlisle Aug 4 '12 at 12:42
  • oh also align is a complete math environment ot should not be inside equation. Finally when making a MWE pleas include the \documentclass and \usepackage .. end{document} it avoids misunderstandings and makes it easier for anyone trying to answer. – David Carlisle Aug 4 '12 at 12:49

Instead of using a tabularenvironment to position the objects, there is also the possibility to make the graphics part of the math formula, for example like this:

\begin {aligned}
\vec{a} \bullet \vec{b}& = |\vec{a}| \cdot |\vec{b}| \cdot \cos(\phi) \\
                       & = a_x  \cdot b_x + a_y \cdot b_y + a_z \cdot b_z \\
            \cos(\phi) & =  \frac {\vec{a} \bullet \vec{b}}{|\vec{a}| \cdot  |\vec{b}|}\\
                       & = \frac {a_x  \cdot b_x + a_y \cdot b_y + a_z \cdot b_z}{\sqrt{a_x^2 + a_y2 + a_z^2}\sqrt{b_x^2 + b_y^2 + b_z^2}}
\end {aligned}
\raisebox{-15mm}{\includegraphics[keepaspectratio = true, scale = 1] {dotp.jpg}}

The \qquad is used to get some whitespace (2em) and \raisebox is only there is you have to adjust the picture vertically.
