The Equation Editor enables users to insert mathematical equations within the HTML Editor. It supports the input of MathML and LaTeX, and includes a graphical editor where you can visually create equations. Depending on your org settings, you may not have access to all input methods.

**Important** The Equation Editor in Pilot 10.2 and onward does not require* Java support or have specific browser compatibility considerations.

*Note, existing equations created before Pilot 10.2 will still require Java Applet support but are up-converted to MathML upon an edit.

## MathML

MathML is a standard adopted by the World Wide Web Consortium (W3C). It uses XML to describe mathematical notation by capturing both its structure and content. This enables MathML to support visual display and assistive technology access.

As a standard, Pilot stores and displays all equations in the MathML format, regardless of the format you use to enter equations. Pilot uses the MathJax JavaScript engine to display MathML equations.

Go to http://www.mathjax.org to learn more about MathJax features.

NoteVersions 9.4.1 and higher of Pilot only support MathML 3.0 markup. You might need to update existing equations if you wrote them using MathML 2.0 markup.

## LaTeX

LaTeX is a typesetting system based on TeX. It provides a text syntax for complex mathematical formulae. Pilot stores equations entered in LaTeX format as MathML to ensure consistency and accessibility.

## Graphical Equation Editor

The Graphical Equation Editor is a Javascript-based application that features a tool bar equipped with a selection of buttons. This tool bar provides the necessary elements to construct your equations quickly and easily. Each button in the Equation Editor tool bar opens a palette of related mathematical symbols.

Before using the Graphical Editor:

- Ensure that you have installed the latest version of your internet browser and that you enable Javascript.
- Disable any software or browser settings that block pop-up windows.
