Creating complex mathematical equations that can be resized on screen or read out loud by screen readers is easy within Canvas. One simply inserts equations in the language Latex. For example, the code

\[\int_{-\infty}^{\infty} e^{-x^2} dx = \sqrt{\pi}\]

produces the equation,

\[\int_{-\infty}^{\infty} e^{-x^2} dx = \sqrt{\pi}.\]

This equation is rendered by the MathJax display engine, a joint venture of the American Mathematical Society (AMS) and the Society for Industrial and Applied Mathematics (SIAM).

Another advantage of typing lecture notes directly into Canvas (effectively as HTML) is that the text reflows automatically regardless of display device (computer, laptop, tablet, phone...) Those who like printed notes to scribble on can always print from their browser!

By contrast, the commonplace method of producing lecture notes (PDF Latex) produces fixed-width pages and equations that are unintelligible to screen readers. The printout looks perfect, but the student has no control over how they consume the material.
