Math DragOn

Math DragOn is an application that combines the ease of a portable calculator with the power of a smartphone. The app features a very intuitive way of entering calculations with drag-and-drop using the touch screen of the smartphone. The calculations can not only be approximated, like a regular calculator would do, they can also be evaluated symbolically. For example: calculating the derivative of x^2 will give a nice 2x as result.

FEATURES:
- An easy-to-use drag-and-drop interface for composing calculations
- An easy-to-use keyboard, specialised for entering constants and variables
- The operators add, subtract, multiply, divide, power, root, derivative and integral
- The functions sin, cos, tan, arcsin, arccos, arctan, log and ln
- Favourites, save or load formulas you use often
- Exact evaluation and approximation: you can either evaluate an expression exactly or you can approximate the answer
- Substitute variables in your formulas
