(Note: Microsoft Mathematics can also be used independently of OneNote)
Microsoft OneNote has many excellent features that support note-taking and searchability, but there are too many features to list in one post. This post will focus on Microsoft Math and OneNote. First of all, there is a built in calculator in OneNote that can be used when typing. Just type the calculations, add an equals sign and press enter:
(Note that trigonometric functions in OneNote are in degrees rather than radians.) For a list of mathematical operations and supported functions, check out the informational page at Microsoft.com.
Microsoft OneNote makes it easy to ink mathematics using the “Ink to Math” option:
It does pretty well at guessing what you mean – but the more information it has, the better it can guess. So expect to see it adjust frequently as you write.
Once you are comfortable with the Ink to Math feature, using Microsoft Mathematics can give many more options. Microsoft Mathematics is a free download and can be used independently, but once you have installed it then you can also install the add-in for OneNote. This gives many options. You can use the add-in to graph equations.
You can also use it to factor or expand polynomial expressions, find derivatives or integrals, or even plot graphs in 2D or 3D:
The best part about this is that you can use this in class as a substitute for chalk and blackboard, and then print the notes to pdf so the students can use them as a resource, or to create their own activities in OneNote.
