# Load the MathJax library and typeset math expressions — withMathJax

withMathJax(...)

### Arguments

... |
any HTML elements to apply MathJax to |
---|

### Description

This function adds MathJax to the page and typeset the math expressions (if
found) in the content `...`

. It only needs to be called once in an app
unless the content is rendered *after* the page is loaded, e.g. via
`renderUI()`

, in which case we have to call it explicitly every
time we write math expressions to the output.

### Examples

withMathJax(helpText("Some math here $$\\alpha+\\beta$$")) # now we can just write "static" content without withMathJax() div("more math here $$\\sqrt{2}$$")
