Draw graphs of math functions with Math Assistant in OneNote

Graph handwritten or typed equations with Math Assistant in OneNote. You can even manipulate variables to see the visual effect of changes, turning Math Assistant into a powerful math coach.

Note: This feature is only available if you have a Microsoft 365 subscription. If you are a Microsoft 365 subscriber, make sure you have the latest version of Office.

Your browser does not support video.

First, create your equation using ink or text

In the Draw tab, write or type your equation. Use the Lasso Select tool to draw a circle around the equation. Then select Math. This will open the Math Assistant pane.

From the Select an action drop-down menu in the Math pane, select Graph in 2D or Graph Both Sides in 2D.

Graph options in the Math pane

To adjust the graph generated by Math Assistant, do any of the following (where available):

Graph options in the Math Assistant pane

  • Select (or press and hold) and then drag the graph in any direction to move its position.

  • Click or tap the + and – magnifying glass buttons as often as needed to change the values of the parameters in your equation by zooming in or out.

Note:  If you’re using OneNote on a touchscreen device, you can also adjust the graph with your fingers. Use a single finger to move the position of the graph, or pinch-zoom with two fingers to change the magnification level. In OneNote for the web, you can use the arrows at the sides of the graph to reposition it.

  • Click or tap the double-arrow Reset icon to reset the graph to its original state.

  • When the graph looks the way you want, click or tap Insert on Page to place it as a screenshot on your current page.

Note: To change how a graph is expressed (degree, radian, gradians), click or tap Settings while the Math pane is open.

Advanced Graphing Features

Other features may be available depending on the type of your graph.

  • Read x-y values:  Hover over a point on the graph line to see x and y values in OneNote for Windows 10. In OneNote for the web, click on a line to see the values.

    Display of x and y coordinates on the graph.

  • Manipulating parameters:  If you have an equation with parameters, such as ax+b, use the plus + and minus - signs below the graph to change the a and b values.

    Manipulate parameters of a and b on a graph.
  • Key graph features: Math Assistant calculates interesting information about the graph, such as zeros, intercepts, minima, maxima, and more. Use the checkboxes to select which features you'd like to display on the graph.

Problem types you can graph in 2D

When you use Math Assistant in OneNote, you'll notice that the Select an action dropdown beneath the equation changes depending on your selected equation. The following problem types can be graphed in 2D with Math Assistant.

Note: This feature is only available if you have a Microsoft 365 subscription. If you are a Microsoft 365 subscriber, make sure you have the latest version of Office.

Expressions

(with variable)

Equations

You can Graph in 2D or Graph both sides in 2D when working with equations.

Select Graph in 2D to see the equation solution. 

  equation reads 3x-2=5

Select Graph both sides in 2D to view a graph of two functions on opposite sides of the equal sign.

Systems of equations

screenshot of math assistant generated graph showing the equations 3 x plus 7 y equals 5 and 2 x minus y equals 4. the graph shows two intersecting lines, one purple and one red.

Polar coordinates

To graph a function in polar coordinates, r needs to be expressed as a function of theta.screenshot of math assistant generated graph of the equation r equals 1 plus cosine 60. the graph has 6 petals like a flower

Inequalities

You can Graph in 2D or Graph both sides in 2D when working with inequalities.

Select Graph in 2D to see the inequality's solution.

Select Graph both sides in 2D to view a graph of two functions on opposite sides of the comparison sign.

screenshot of math assistant generated graphs of the inequality 2 minus 3 x is greater than or equal to 6 minus x squared. The former in purple and the latter in red.
