The CodeCogs Equation Editor can be used in a range of circumstances to create beautifully formatted mathematical equations in either LaTeX or MATHML. Every day, thousands use the Equation Editor to create millions of equations, making it the world's #1 online editor.

Integration with CK Editor is provided through a simply plugin that dynamically loads the equation editor when needed.

### Usage

- To create a new equation, first click within the text area where you need to add the equation.
- Click the fx button on the CK Editor toolbar. This launches the CodeCogs Equation Editor, which you can also see here http://www.codecogs.com/eqneditor
- Create your equation.
- Select 'Copy to document' to insert the equation into your document at the cursor position.
- Double-click existing equations to edit them in the Equation Editor.

### Installation

- Download the equation plugin and uncompress it to your desktop or server.
- Find the folder where you installed CK Editor. For our purposes we will assume this is ~/ckeditor.
- Open the CK Editor plugins folder, ~/ckeditor/plugins and copy in the directory equation from the uncompressed equation_v1.2.zip folder.
- Modify the config.js to load the plugin by adding config.extraPlugins = 'equation'.
- The equation editor buttion (fx) will now appear in the 'insert' group.
- Alternatively, you can add the 'Equation' button to a custom toolbar, i.e. CKEDITOR.replace( 'editor1', { toolbar : [ [ 'Equation', 'Bold', 'Italic' ] ] });
