Problem types supported by Math Assistant

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. Here are some of the problem types supported depending on the equation you're trying to solve.

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.

Arrays

For a list of real numbers, all of the below are supported.
 

  • Evaluate

  • Sort

  • Mean

  • Median

  • Mode

  • Sum

  • Product

  • Greatest Common Factor

  • Least Common Multiple

  • Variance

  • Standard Deviation

  • Minima

  • Maxima

    alternate text

    For polynomials, the supported actions are Greatest Common Factor and Least Common Multiple. You can also choose to Graph in 2D to view the graphs of all your functions.

Expressions

For any expression, the available actions are:

  • Evaluate

  • Verify

  • Expand (if applicable)

  • Factor (if applicable)

  • Graph in 2D (only available if there is a variable)

  • Differentiate (only available if there is a variable)

  • Integrate (only available if there is a variable)

    alternate text

Equations and inequalities

For equations and inequalities, the following actions are available:

  • Solve for {your variable}

  • Graph Both Sides in 2D — Each of the sides of the equality or inequality is graphed as a separate function.

  • Graph in 2D — A graph of the equation or inequality solutions

  • Graph Inequality — Marks the solution area on the graph

Systems

It is important to have an equal number of equations and variables to ensure the correct functions are available. Systems can be written in two different ways: 

  1. One below another, with or without a big brace before them

  2. In one line divided by a comma

Derivatives and integrals

Derivatives can be written either with d/dx before the function, or with a prime mark.

alternate text

The actions available for derivatives and integrals are:

  • Evaluate

  • Graph in 2D

  • Differentiate

  • Integrate (for derivatives only)

    alternate text

Matrices

Matrices can be written with square or round brackets. The following actions are supported for matrices:

  • Evaluate

  • Calculate Determinant

  • Invert Matrix

  • Calculate Trace

  • Transpose Matrix

  • Matrix Size

  • Reduce Matrix

Matrix equations are not currently supported.

Graphing in polar coordinates

To graph a function in polar coordinates, r needs to be expressed as a function of theta.

Complex mode

Note: Select Settings to switch between real numbers and complex numbers.

For complex expressions and numbers containing imaginary unit i, the following actions are available.

  • Evaluate

  • Real Part

  • Imaginary Part

  • Conjugate

  • Modulus

  • Argument

  • Differentiate (only if there is a variable)

  • Integrate (only if there is a variable)
