Last summer we introduced Ink math assistant in OneNote—a digital tutor that gives you step-by-step instructions on how to solve your handwritten math problems. Today, we are excited to announce that Ink math assistant can draw graphs of your equations, all within OneNote for Windows 10.

Now, when you write your math equations, the Ink math assistant quickly plots an interactive graph to help you visualize those difficult math concepts. You can zoom in and move the graph to observe intersection points or change values of parameters in your equations to better understand how each of them reflects on the graph. Finally, you can save a screenshot of the graph directly to your page to revisit it later.

Five steps to graph an equation in OneNote

  1. Begin by writing your equation. For example: y=x+3 or y=sin(x)+cos(2x).
  2. Next, use Lasso tool to select the equation and then, on the Draw tab, click the Math button.
  3. From the drop-down menu in Math pane, select the option to Graph in 2D. You can play with the interactive graph of your equation—use a single finger to move the graph position or two fingers to change the zoom level.
  4. Use + and buttons to change the values of the parameters in your equation.
  5. Finally, click the Insert on Page button to add a screenshot of the graph to your page.

Availability: Ink math assistant is available in OneNote for Windows 10, for Office 365 subscribers.

As always, we would love to hear your feedback, so please make comments below or suggest and vote on future ideas on OneNote UserVoice page.

  1. OneNote for windows 10 for office 365 subscribers? That’s confusing the two-OneNote situation even more!

  2. This is a really super feature! Great stuff.
    I’m a bit perplexed though at the decision to have this only on the Win10 app. Our users will be almost exclusively online or 2013/2016 desktop. Particularly for users on the 2016 client, many will have chosen that thinking they have the fullest feature set. The multi-speed approach is very confusing – for example, the ‘our support page’ link above tells you that you need an O365 subscription and has a link to help you make sure you have the latest version of Office which suggests you upgrade to Office 2016! What are the plans to bring this to 2016/Online? Should we be advising users to opt for the Win10 app? Is the longer term plan to persist both desktop versions?

  3. This is super cool! My AP Calculus lectures are about to become more interesting.

    Will I be able to graph more than one function on a graph?
