OneNote Latex Math Support

Getting into Equation Mode use <alt> and = to get into the equation editor.

Radicals: $\sum_{i=0}^n i^2 = \frac{(n^2+n)(2n+1)}{6}$ 

$x = {-b \pm \sqrt{b^2-4ac} \over 2a}$ is generated from: x = {-b \pm \sqrt{b^2-4ac} \over 2a}

For example, to get the $\sqrt[6] {64}$ (6th root of 64), you would type: \sqrt(6&64)

    See MathJax support here: https://math.meta.stackexchange.com/questions/32647/how-to-write-roots-other-than-square-roots-in-mathjax

Note that the above is the UniCode Math notation. The Latex notation of \sqrt[6]{64} does not work in OneNote

Aligning to a character, using UniCode Math

\eqarray(x+1&=2@1+2+3+y&=z@3/x&=6)<space>

which resolves to:

This can be done using the MathJax as follows:

$$\begin{eqnarray} 

y &=& x^4 + 4      \nonumber \\

&=& (x^2+2)^2 -4x^2 \nonumber \\

&\le&(x^2+2)^2    \nonumber

\end{eqnarray}$$
