 katex.render("c = \\pm\\sqrt{a^2 + b^2}", element);

+#### Rendering options
+
+You can provide an object of options as the last argument to `katex.render` and `katex.renderToString`. Available options are:
+
+- `displayMode`: `boolean`. If `true` the math will be rendered in display mode, which will put the math in display style (so `\int` and `\sum` are large, for example), and will center the math on the page on its own line. If `false` the math will be rendered in inline mode. (default: `false`)

+For example:
 
 ```js
-katex.render("\\displaystyle " + formula, element);
-// OR
-var html = katex.renderToString("\\displaystyle " + formula);
