MathJax is an open source JavaScript display engine that translates mathematical markup into accessible equations on the web. Pressbooks features a native integration with MathJax that renders math expressions with MathJax in the webbook and creates accessible image versions of equations and other mathematical markup for its EPUB and PDF exports.\n

<\/a>Display LaTeX with MathJax<\/h1>\n
NOTE: <\/strong>MathJax is not available on Pressbooks.com. All books published on Pressbooks.com have the WP QuickLaTeX plugin enabled by default.<\/div>\nThere are two ways to use LaTeX syntax in MathJax:\n\nShortcode syntax:\u00a0<\/strong>\n[la\u200btex]<\/strong>e^{i \\pi} + 1 = 0[\/lat\u200bex]<\/strong><\/code>\n\nDollar sign syntax:\u00a0<\/strong>\n$latex<\/strong> e^{i \\pi} + 1 = 0$<\/strong><\/code>\n\nYou can click the LaTeX button in the visual editor to input LaTeX directly or add the syntax delimiters to an expression manually. Note that equations will not display fully formatted in the editor. However, you can view the webbook or export your files at any time to see how the equations appear.\u00a0 Learn more about LaTeX from their documentation<\/a>.\n

<\/a>Display AsciiMath with MathJax<\/h1>\nMathJax is capable of rendering AsciiMath, an client-side markeup language for mathematics. There are two ways to use AsciiMath syntax in MathJax:\n\nShortcode syntax:\u00a0<\/strong>\n
[asciimath]<\/strong>e^{i \\pi} + 1 = 0[\/asciimath]<\/strong><\/pre>\nDollar sign syntax:\u00a0<\/strong>\n
$asciimath<\/strong> e^{i \\pi} + 1 = 0$<\/strong><\/pre>\nAsciiMath can be drafted directly in the visual editor. Learn more about AsciiMath from their website<\/a>.<\/span>\n
<\/a>Display MathML with MathJax<\/h1>\nMathML is an XML-based mathematical markup language. To render MathML with MathJax, input the relevant expression using the Text Editor<\/a>:\n\nExample:\u00a0<\/strong>\n
<math><mrow><mrow><msup> <mi>x<\/mi> <mn>2<\/mn> <\/msup> <mo>+<\/mo><mrow><mn>4<\/mn><mo>\u2062<\/mo><mi>x<\/mi><\/mrow><mo>+<\/mo><mn>4<\/mn><\/mrow><mo>=<\/mo><mn>0<\/mn><\/mrow><\/math><\/pre>\n
Learn more about MathML from the W3C's documentation page<\/a>.<\/div>\n
<\/a>Configure MathJax Settings<\/h2>\n\"\"Click 'Settings -> MathJax<\/strong>' to access your MathJax settings page. If you do not see a MathJax settings option, this usually means that your book is using the WP QuickLaTeX plugin.\n\nThe MathJax settings page provides examples of support syntax and allows you to to change the text color of all equations in your book and select the font used when generating images for use in EPUB and PDF exports.\n
<\/a>Use MathJax's Accessibility Features<\/h2>\nWithin the webbook, readers can right click any equation rendered in MathJax to access additional display options and accessibility features. Options include the ability to magnify any equation on click or hover, the ability to display the math in HTML, SVG, and other formats, and more. Learn more about MathJax's accessibility features from their documentation.<\/a>\n\n\"MathJax\n
<\/a>Render LaTeX with WP QuickLaTeX<\/h1>\nWP QuickLaTeX is a plugin that allows you to write native LaTeX syntax directly into your books without wrapping shortcodes around every part of every equation.\n
Note: <\/strong>WP QuickLaTeX is the default mathematics rendering option for Pressbooks.com users and can be used as an optional replacement for MathJax within individual books on other networks.<\/div>\n \n\nTo enable the WP QuickLaTeX plugin:\n
    \n \t
  1. \"\"Click 'Plugins'<\/strong> from left-hand menu of your screen<\/li>\n \t
  2. Click 'Activate<\/strong>' for WP QuickLaTeX<\/strong><\/li>\n<\/ol>\nIf you do not see this option, please contact your Network Manager.\n\nOnce WP QuickLaTeX has been activated for your book, there are two recommended methods for rendering LaTeX expressions:\n
      \n \t
    1. Use the<\/strong> [la\u200btex]<\/code> shortcode.<\/strong> A sample expression would look like this: [la\u200btex]x^2 + y^2 = z^3[\/lat\u200bex]<\/code>.<\/li>\n \t
    2. Add a <\/strong>[latexpage]<\/code> shortcode to the top of your chapter. <\/strong>Adding [latexpage] to the top of a chapter will ensure that everything written in LaTeX syntax will be rendered by WP QuickLaTeX without additional LaTeX syntax delimiters. For example, if you were to input the following:<\/li>\n<\/ol>\n
      \n
      [latexpage]\nAt first, we sample $f(x)$ in the $N$ ($N$ is odd) equidistant points around $x^*$:\n\\[\nf_k = f(x_k),\\: x_k = x^*+kh,\\: k=-\\frac{N-1}{2},\\dots,\\frac{N-1}{2}\n\\]\nwhere $h$ is some step.\nThen we interpolate points $\\{(x_k,f_k)\\}$ by polynomial\n\\begin{equation}\u00a0\\label{eq:poly}\nP_{N-1}(x)=\\sum_{j=0}^{N-1}{a_jx^j}\n\\end{equation}\nIts coefficients $\\{a_j\\}$ are found as a solution of system of linear equations:\n\\begin{equation}\u00a0\\label{eq:sys}\n\\left\\{ P_{N-1}(x_k) = f_k\\right\\},\\quad k=-\\frac{N-1}{2},\\dots,\\frac{N-1}{2}\n\\end{equation}\nHere are references to existing equations: (\\ref{eq:poly}), (\\ref{eq:sys}).\nHere is reference to non-existing equation (\\ref{eq:unknown}).<\/pre>\n<\/div>\nWP QuickLaTeX would render something which looks like this:\n\n\"Example\n
      \n\nThere are a few places in your book where you should not use [latex]<\/code> shortcodes:\n
