Mathematical Playground Lite vs Drawing with Math

This is an educational app that is useful for exploring three dimensional shapes. Have you ever had difficulty drawing three dimensional shapes? This app may help you study about shapes. Since this app is the lite version, less features are available than the full-version. But all shapes are available. And you can cut, expand shapes, and also receive shape data from the full-version of this app. --- This app runs on… [iPhone] iPhone 4s or newer. [iPad] iPad 2, iPad 3rd generation or newer, iPad mini series, iPad Air series, iPad Pro series. [iPod touch] iPod touch (5th generation or newer). [OS] iOS12.0 or elder.

Our “Drawing with Math (Vector and Pixel Art)” app combines two main components: * uniquely versatile image editors, * various methods of linear transformations of both user-entered and system images. Image editors are available in vector and pixelated forms. The editors offer such options as: * free drawing, * entry of all standard shapes, * entry of regular Cartesian, polar, or parametric function into image editor. List of several visually appealing functions is provided. The App stores 10 most recent user entries for each type. Vector images can be linearly transformed in a variety of user-defined ways: * 2x2 matrix, * eigenvalues and eigenvectors, * rotation by degree, * reflection across a given vector. Pixelated images can be compressed by segments to user-selected rank. Mathematical context for the above is provided, whenever possible. Explanation of image compression algorithms requires significant understanding of Linear Algebra, and is available in our “Matrix Solver Step by Step” app. Several bonus images with animations and editable greeting cards are also available.
