How do I use Math Assist?
To use Math Assist, make sure to turn Math Assist on by tapping on the Pen icon >Pen icon > Math Assist and toggle Suggestions on. Once this feature is on, following the next steps to use Math Assist:
- Write a maths equation with an equals sign.
- Once recognized as a maths equation, the equation will glow blue.
- Tap on the blue glow to open the Math Assist menu, from here you can choose a solving strategy and the answer will appear in handwriting
Note: Math Assist is only available in notebooks where the language is set to English.
You can also set and change variables to see them be updated live in your equations! For example, changing the value of s changes the answer below:
You can also change the format an answer is presented in through the Math Assist menu!
How can I change the equation once it has been recognized for Math Assist?
If Math Assist incorrectly recognized your equation, or you just wish to change it, you can modify the LaTeX which is the computer readable version of your handwritten equation.
- In the Math Assist menu, tap on the edit LaTeX button to edit or correct an equation.
I think the Math Assist has incorrectly calculated something, how do I check this?
Under most circumstances, AI Math Assist should not make mistakes in a mathematical sense. With that being said, there are definitely a few things to bear in mind when using this feature (which can often explain why Math Assist has seemingly made a mistake:
- The math you've written has not been properly recognized by the app: This is the most common issue which can cause problems with the Math Assistance. In short, if the app misreads your writing, it can result in lines of your equation being improperly underlined as incorrect.
- You are trying to complete some forms of mathematics that the app doesn't support.
How do I disable Math Assist?
To disable Math Assist, tap on the Pen icon > Math Assist and toggle Suggestions off.
Which topics are supported by Math Assist?
Math Assist can help with simple arithmetic, such as + , – , × , ÷ .
If the solution is not an integer, you will have the option to choose between fractions, mixed fractions and decimals.
Percentages are also supported.
You can define one or more variables on one page, and substitute them into future computations as needed.
If you overwrite an existing variable, the most recent definition will prevail, e.g.
Limitations
Math Assist does not support the use of word variables. In the following example,
is parsed as , which is why the first term is simplified as
.
When solving an equation, you can pause at any step and use Math Assist to complete the step, as shown in the example below:
Math Assist can be used to solve much more complicated equations, such as quadratic, cubic and quartic equations.
When multiple solutions exist, Math Assist will present all of them in brackets.
As with the case of simple equations, you can let Math Assist take over at any intermediate step in your calculations.
You can define a system of equations, and Math Assist can solve it simultaneously.
For system of equations carrying multiple solutions, Math Assist will group together simultaneous solutions using nested brackets.
You can use Math Assist to expand or factorise algebraic expressions.
If your input is a fraction, and both the numerator and denominator are univariate polynomials, you can use Math Assist to perform partial fraction decomposition.
Math assist supports both degrees and radians.
You can also apply well-known identities to expand or simplify trigonometric expressions.
You can take absolute values on variables.
You can also solve equations involving absolute values.
Math Assist supports the use of ± sign as a shorthand for “plus or minus” operation, e.g.
You can use the ± sign in any part of your equations.
Both summation and product signs are supported.
The lower and upper bounds need not to be numbers; they can be variables, or infinity.
You can also define nested summations, with the inner index depending on the outer index.
Math assist automatically converts very small and very large values into scientific notations.
The coefficient is capped to 3 decimal places.
You can define functions with reserved letters f, g, h, F, G, H, as shown below.
You can also calculate function inverses, should an inverse exist.
Limitations
Currently we do not support functions defined with letters outside of f, g, h, F, G, H. So v(x) will simply be parsed as .
We also do not support functions defined on another function, so the following will not give any suggestions:
You can compute limits
as well as one-sided limits
You can also apply limits on functions.
Math Assist supports differentiation via Leibniz’s and Lagrange’s notation.
|
Leibniz’s notation |
Lagrange’s notation |
You can also perform implicit differentiation
Limitations
Math Assist does not support differential equations; currently, it also does not support differentiation of nested functions, e.g..
Math Assist supports the calculation of indefinite, definite and improper integrals.
You can also integrate to infinity, should such a limit exists.
Limitations
Some hard to evaluate integrals may result in approximate solutions, e.g. the true value of the following expression is π
Additionally, Math Assist currently does not support integration of functions, e.g.
Not supported
- Matrix algebra
- Differential equations
- Geometry
- Inequalities
