Recognize Handwritten Equations with MyScript MathPad

Years ago, I shared about Web Equation, a website that lets you hand write equations and solve them via Wolfram Alpha. In this post, I am going to introduce to you another handwritten equation recognition app, the MyScript Mathpad.

MyScript Mathpad is a handwriting recognition app specialized for mathematics expressions. MyScript Mathpad automatically converts handwritten mathematical expressions and equations to their digital equivalent. It can recognize more than 200 symbols and operators.

via iTunes

Equations created with MyScript Mathpad can be exported to Latex and MathML.  It can also be shared through Twitter, Facebook, Google+ and other social media.

There are two features that I like about MyScript Mathpad. The first one is its scratch-out and strike-through gesture editing.  If you want to delete something, all you have to do is to scratch-out the expression you want and it’s gone. The second one is its support for left-handed persons.

MyScript MathPad is compatible with iPad, iPhone, and iPod Touch running in iOS 6.0 or later.

It’s FREE!


Understanding Point Symmetry

In the previous post, we have learned about line symmetry. In this post, we are going to learn about point symmetry, another type of symmetry.

If a figure is rotated 180 degrees about a point and it coincides with its original position, then it is said that the figure has point symmetry. The point of rotation is called the point of symmetry.

The figure below shows the point symmetric polygon ABCDEF rotated clockwise about P, its point of symmetry. The polygon outlined by the dashed line segments shows its original position.  Continue reading…


Understanding Line Symmetry

Many people believe that symmetry is beauty. Nature is full of symmetric objects. There are many man-made structures that are also symmetric. In this post, we are going to discuss some of the basic mathematical properties of symmetric objects. We will limit our discussion to line symmetric objects.

Line Symmetry

A figure is line symmetrical when it can be folded along a straight line such that the folded shapes fit exactly on top of each other. The fold line is called the line of symmetry.

When a symmetric figure is folded along its line of symmetry, the parts that are on top of each other are called the corresponding parts. In the polygon below with line of symmetry AB, points C and D are corresponding points, segments GB and HB are corresponding sides, and angle G and angle H are corresponding angles. Since the folded shapes fit exactly on top of each other, the corresponding angles are congruent and their corresponding sides are also congruent.  Continue reading…
