### 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)

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:

$$\begin{eqnarray} y &=& x^4 + 4 \nonumber \\ &=& (x^2+2)^2 -4x^2 \nonumber \\ &\le&(x^2+2)^2 \nonumber \end{eqnarray}$$

### OneNote Files From Locally stored to Cloud, and Back to Local Storage

OneNote for Office 365 has the capacity to store the Notebook locally.

For a locally stored notebook, to be shared one can do the following:

Open the locally stored notebook in OneNote for Windows 10. It will automatically sync up to OneNote on the web.

At some point, you may want to be able to create a backup of this: Open OneNote for Office 365, go to File | Open | Sign In, then Search for the Notebook. Once it is open, go to File | Export | Notebook, select OneNote Package (*.onepkg). Store that to a location. You can then open it with OneNote 365.
