 # Use the Latex Macro

## Add a Latex macro to a page

1. Navigate to the page you would like to edit.

2. Click the Edit icon in the top-right of the page.

3. Click the position where you want to insert LaTeX content.
4. Select Insert > View More in the Confluence editor.

5. Select the LaTeX macro in the Select Macro screen. 6. Customize the appearance of your equations or formulas using the following parameters:

• Block Equation Alignment: Select the alignment for block equations. Options include Left, Center (default), and Right.

• Inline Equation Alignment: Select the alignment for inline text or equations. Options include Left (default), Centerand Right.

7. Add the desired text or equations in the Insert Text input area. Multiple formulas or equations can be included inside a single macro, and multiple macros can be included within a page.

8. Click Save. A macro placeholder is displayed. 9. Click Publish to view the macro rendered on the page. ### Edit the macro

To make changes to the macro parameters or text content, click the macro placeholder, then click the Edit icon. Make the required changes, then click Save.

### Inline vs. block formatting

To display an inline equation, a single dollar sign must be placed on either side of text within the macro, e.g. $ax^2 + bx + c = 0$.

Block equations must include a double dollar sign on either side of the text to be rendered, e.g.  $$x = {-b \pm \sqrt{b^2-4ac} \over 2a}$$. See the examples below.

#### Inline #### Block ### Formatting examples

#### Matrix and array

You can use an array to format equations similar to the example below.

text\begin{array}{lcl}
z & = & a \\
& = & a \\
f(x,y,z) & = & x + y + z
\end{array} A matrix can be applied to arrange formulas in columns with different delimiters such as the centered bracketed matrix below.

text\begin{bmatrix}
\alpha& \beta^{*}\\
\gamma^{*}& \delta
\end{bmatrix} #### Color

You can add color to your LaTeX formatting by adding a color parameter, e.g.  $\color{red}{ax^2 + 1 + 55 + bx + c =0}$. ### Packages

To provide extra functionality for the LaTeX macro, several LaTeX packages have been included.

These include Unit, mhChem, and Physics. To apply the required format, simply follow the formatting examples below.

#### Unit #### mhChem #### Physics ### Limitations

Due to a Confluence limitation, the Export to PDF functionality does not work with macros that require JavaScript to render on the Confluence page, e.g. LaTex. If you want to preserve your content in PDF format, we recommend that you use your browser’s built-in functionality to print to PDF.
