# How do I show equations in a page?

SiteBuilder supports LaTeX markup, which you can use to show mathematical equations in web pages.
1. Go to the page where you wish to show an equation.
2. Go to Edit > Edit centre content (or Edit right content).
3. Place your cursor in the content editor where you wish to insert the equation.
4. In the toolbar, select Insert a… > Maths equation (LaTeX).
5. Enter the LateX markup for your equation in the text box:

6. Select the Insert button. The markup displays in the content editor wrapped inside the $ tag. For example: [latex] \Large\varepsilon=\sum_{i=1}^{n-1}\frac1{\Delta x}\int_{x_i}^{x_{i+1}}\left\{\frac1{\Delta x}\big[(x_{i+1}-x)y_i^\ast+(x-x_i)y_{i+1}^\ast\big]-f(x)\right\}^2dx$
7. When you have finished editing your page, select the Publish button in the toolbar. You should see an image of your equation in the published page. For example:

$\Large\varepsilon=\sum_{i=1}^{n-1}\frac1{\Delta x}\int_{x_i}^{x_{i+1}}\left\{\frac1{\Delta x}\big[(x_{i+1}-x)y_i^\ast+(x-x_i)y_{i+1}^\ast\big]-f(x)\right\}^2dx$
