LaTeXIt Image Width

Question

I'm not much of a LaTeX jockey, but I use it to typeset equations via LaTeXIt. I'm noticing that LaTeXIt will cut off the typeset image if it exceeds a certain width - I've looked for a document width property but can't find one. I'd prefer to not split the equation across lines, but I'd like the image to capture the full width of the typeset equation. Is there a trick to remove this constraint?

I don't think I've modified the standard preamble, which I think LaTeXIt says is:

\documentclass[10pt]{article}
\usepackage{color} %used for font color
\usepackage{amssymb} %maths
\usepackage{amsmath} %maths
\usepackage{esdiff}
\usepackage[utf8]{inputenc} %useful to type directly diacritic characters

An example of a silly long equation that gets cut off is:

\operatorname{I_{{Load}}}{\left (t \right )} = \frac{C_{1}}{2 L} \left(- R_{{load}} - \frac{1}{\sqrt{C_{{L}}} \sqrt{C_{{R}}}} \sqrt{C_{{L}} C_{{R}} R_{{load}}^{2} - 4 C_{{L}} L - 4 C_{{R}} L}\right) e^{\frac{t}{2 L} \left(- R_{{load}} - \frac{1}{\sqrt{C_{{L}}} \sqrt{C_{{R}}}} \sqrt{C_{{L}} C_{{R}} R_{{load}}^{2} - 4 C_{{L}} L - 4 C_{{R}} L}\right)} + \frac{C_{2}}{2 L} \left(- R_{{load}} + \frac{1}{\sqrt{C_{{L}}} \sqrt{C_{{R}}}} \sqrt{C_{{L}} C_{{R}} R_{{load}}^{2} - 4 C_{{L}} L - 4 C_{{R}} L}\right) e^{\frac{t}{2 L} \left(- R_{{load}} + \frac{1}{\sqrt{C_{{L}}} \sqrt{C_{{R}}}} \sqrt{C_{{L}} C_{{R}} R_{{load}}^{2} - 4 C_{{L}} L - 4 C_{{R}} L}\right)}

In this case it is not well formatted because it is machine generated. The result I'm seeing is:

One of the many possibilities to make your code more elegantly.

\documentclass{article}
\usepackage{amssymb}
\usepackage{mathtools}
\usepackage[margin=1in]{geometry} 
\begin{document}


\begin{align*}
I_{\text{load}}(t) &=  \frac{C_{1}}{2 L} \left(- R_{\text{load}} - \frac{1}{\sqrt{C_{{L}}} \sqrt{C_{{R}}}} \sqrt{C_{{L}} C_{{R}} R_{\text{load}}^{2} - 4 C_{{L}} L - 4 C_{{R}} L}\right)\, e^\mu
\end{align*}

where $\mu$ is

\[
\begin{split}
\mu &= \frac{t}{2 L} \left(- R_{\text{load}} - \frac{1}{\sqrt{C_{{L}}} \sqrt{C_{{R}}}} \sqrt{C_{{L}} C_{{R}} R_{\text{load}}^{2} - 4 C_{{L}} L - 4 C_{{R}} L}\right)\\
&+\frac{C_{2}}{2 L} \left(- R_{\text{load}} + \frac{1}{\sqrt{C_{{L}}} \sqrt{C_{{R}}}} \sqrt{C_{{L}} C_{{R}} R_{\text{load}}^{2} - 4 C_{{L}} L - 4 C_{{R}} L}\right) \\
&\cdot e^{{\frac{t}{2L}}\left(-R_{\text{load}} +\frac{1}{\sqrt{C_{L}}\sqrt{C_R}}\sqrt{ R_{\text{load}}^2 -4 C_{L} L-4 C_{R} L}\right)}
\end{split}
\]
\end{document}

One way is to edit the preamble in Preferences > Templates > Preambles to include \usepackage{fullpage} or \usepackage[cm]{fullpage}. For example, you could use the default plus fullpage:

\documentclass[10pt]{article}
\usepackage[usenames]{color} %used for font color
\usepackage{amssymb} %maths
\usepackage{amsmath} %maths
\usepackage[utf8]{inputenc} %useful to type directly diacritic characters
\usepackage[cm]{fullpage}

This will make a wider text block and should fit more text/math symbols per line.
