Ink math assistant, a digital tutor that provide step-by-step instructions to solve handwritten math problems in the OneNote, now begining Thursday, the Ink math assistant can draw graphs of math equations, all within OneNote for Windows 10.

Starting today, the Ink math assistant when you write math equations, now quickly plots an interactive graph to help visualize difficult math concepts. "You can zoom in and move the graph to observe intersection points or change values of parameters in equations to better understand how each of them reflects on the graph," writes the OneNote team.

Finally, also a screenshot of the graph can be directly save to a page to revisit it later.

Below are the steps to graph an equation in OneNote:

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