About MathBrush
MathBrush is an iPad and iPhone app that recognizes mathematical expressions as you draw them. It supports variables and functions, not just numbers, and recognizes a wide range of mathematics, including polynomials, integrals, multiple expressions, and matrices. Save your expressions for later, or export them for a document or website. MathBrush exports LaTeX, MathML and image formats, which can be viewed on-screen or shared by email, AirDrop, Messages or any sharing support App available on your device. MathBrush also allows the sharing of a MathBrush sheet (.mbs) by email or AIrDrop to be opened on other devices with the MathBrush App to continue working on the same sheet.
You can use MathBrush to manipulate your expressions and obtain results with the help of a Computer Algebra System (CAS). MathBrush uses SAGE as the backend CAS to manipulate the input expression and the results. You can share the results of your manipulation. MathBrush dynamically generates a set of applicable operations based on the type of the expression. Examples of supported operations are factor, expand, differentiate, plot, determinant, eigenvalues, eigenvectors. You can register for a free trial to the manipulation feature with no obligation for subscription.
MathBrush allows you to train the recognizer to your handwriting and create a profile. Multiple profiles can be created and at any time one of them can be used as the default. You can edit your profiles at any time by adding more symbols or changing existing ones.
MathBrush currently supports the following types of expressions:
•Polynomials
•Fractions
•Square roots
•Equations and inequalities
•Unary negation
•Multiplication (using * or invisible times operator)
•Superscripts
•Subscripts (must be variables or numbers)
•Indefinite and definite integrals
•Indefinite and definite sums and series
•Matrices
•Trigonometric functions: sin, cos, tan, exp, log, and ln.
•Single-character variables
The free version of MathBrush allows you to enter expressions of up to 25 strokes and to manipulate the expressions with a CAS during the a free trial period. Writing larger expressions and sharing them requires a purchase.

The recognition of symbols in MathBrush depends on previously stored examples of each symbol. The recognizer compares your handwriting against those examples to come up with the correct symbol.
In this version, you can train the recognizer to your handwriting if you find it poorly recognizes one or more of your symbols.
To do that, you will be able to create your own profile and add examples for the symbols of your choice. You can then set this profile to be the active profile. At any time, you can go back to your profile and edit it. You can also delete a profile or create multiple profiles and activate one at any time. This is particularly useful if more than one person uses the iPad. Using your own profile will help improve symbol recognition.
