The Equation Editor is accessible within the HTML Editor, which enables users to insert mathematical and statistical equations into an HTML page. Learning Environment supports the input of MathML and LaTeX, as well as a graphical editor where you can visually create equations. Depending on your org settings, you may not have access to all input methods.

MathML
- The purpose of this tutorial is to explain how to use the Equation Editor tool, and to let you practice using it. You will be using this tool to enter answers that are numbers, expressions, or equations. Before we get started, there are a couple of important things to remember: 1. The tool is not a calculator—it will not perform calculations.
- Equation Editor allows you to enter an algebraic equation of standard mathematical operators and functions, referencing data that is available in the E5071C. Once a valid equation is entered and enabled, the display of the active trace is replaced with the results of the equation, and updated in real-time as new data is acquired.
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, Learning Environment stores and displays all equations in the MathML format, regardless of the format you use to enter equations. Users can choose to display equations as inline MathML or using the Java applet from their preferences. While Firefox supports the display of inline MathML, other browsers require the Java applet to render equations.
To enable the display of equations as inline MathML, go to the Preferences tool and change your Math Display setting in the Appearance & Accessibility tab. See Setting your preferences for more information.
LaTeX
LaTeX is a typesetting system based on TeX. It provides a text syntax for complex mathematical formulae. Learning Environment stores equations entered in LaTeX format as MathML to ensure consistency and accessibility.
Graphical Editor
The Graphical Editor is a Java-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.
Review the following steps prior to using the Graphical Editor:
- Ensure that you have installed the latest version of your internet browser.
- Disable any software or browser settings that block pop-up windows.
- Install the most recent Java Runtime Environment (JRE) from Sun Microsystems Inc. (http://www.java.com/en/download/manual.jsp).

Using the Equation Editor
Access the Equation Editor
- Go to the Advanced tab of the HTML Editor.
- Click the Insert Equation icon.
Create an equation
- Enter a Title for your equation.
- Choose the Math Format you want to use and click Apply. If you choose to switch formats, you must recreate your equation in the new format since the Equation Editor cannot convert your equation to another format.
- Enter your equation and click Refresh Preview to ensure the accuracy of your equation.
- Click Insert.
Tip Save!
Edit an equation
- Select the equation that you want to edit by clicking on the corresponding capital sigma sign.
- Go to the Advanced tab of the HTML Editor.
- Click the Equation Editor icon.
- Make the changes you want to your equation. If you choose to switch formats, you must recreate your equation in the new format since the Equation Editor cannot convert your equation to another format.
- Click Refresh Preview to ensure the accuracy of your equation.
- Click Insert to update your equation.
Delete an equation
- From within the HTML Editor, select the equation that you would like to delete.
- Press the Delete key or click the Cut icon to remove the equation from the HTML page.
This equation editor opens in a pop-up window when you click on the link below. You can enter math characters, symbols or expressions by clicking on the icons provided. A snippet of code appears below. Then edit the code, and type your numbers or variables in it, or some additional text.
After you're done, you can save (download) the gif image to your computer or copy it to a document.
The code is Latex and is familiar to many of us who have used Latex before, but it is fairly intuitive. For example, when you want a fraction and you press the fraction button, you will see the code
Just type your numerator in place of a, and your denominator in place of b. Those can be expressions as well.You can make fractions, exponents, subscripts, square roots and other roots, sums (sigma sign), products (pi sign), integrals and limits. A list of Greek characters is included. The symbol list is fairly basic and includes some basic operation and relation symbols, set theory symbols, and a few arrows.
You can also change the font and the font size and the background color.
