Installation

No Install

Use Overleaf to create latex documents in a web browser.

Partial Install

Download MikTex. It includes the TeXworks editor and will download packages as you use them. This will not take up as much disk space as a full install.

Full Install

Windows

Download TexLive. This is several gigabytes since it includes all the popular LaTex packages and takes a while to install. You'll also need an editor. I recommend installing Atom with the following packages:

  • latex for calling the TexLive compiler
  • language-latex for syntax highlighting
  • pdf-view for viewing the compiled pdf.

Linux

sudo apt install texlive-full

Compile tex documents with

pdflatex [mydocument.tex]

Usage

Fancy Math Font

See this answer.

% Use mathbb for the set of reals R or the set of complex numbers C
% Requires amsfonts
\mathbb{R}

Spaces

See Reference

Spaces in mathematical mode.
 
\begin{align*}
f(x) =& x^2\! +3x\! +2 \\
f(x) =& x^2+3x+2 \\
f(x) =& x^2\, +3x\, +2 \\
f(x) =& x^2\: +3x\: +2 \\
f(x) =& x^2\; +3x\; +2 \\
f(x) =& x^2\ +3x\ +2 \\
f(x) =& x^2\quad +3x\quad +2 \\
f(x) =& x^2\qquad +3x\qquad +2
\end{align*}

Tikz

Tikz is used to draw graphs and other shapes

Drawing over images

\begin{tikzpicture}
    \node[anchor=south west,inner sep=0] (image) at (0,0) {
    \includegraphics[width=.9\linewidth]{my_image.png}
    };<br />
    \begin{scope}[x={(image.south east)},y={(image.north west)}]
        \draw[black,ultra thick,rounded corners] (0.0,0.1) rectangle (0.3,0.5);
        \draw[red,ultra thick,rounded corners] (0.5,0.1) rectangle (0.8,0.5);
        % \draw[help lines,xstep=.1,ystep=.1] (0,0) grid (1,1);
        % \foreach \x in {0,1,...,9} { \node [anchor=north] at (\x/10,0) {0.\x}; }
        % \foreach \y in {0,1,...,9} { \node [anchor=east] at (0,\y/10) {0.\y}; }
    \end{scope}
\end{tikzpicture}
