Dynamic Geometry for Android

8 things about Dynamic Geometry

1. - New Variable: create mathematical variable object, you can enter complex mathematical formulas, execution, subtraction, multiplication, fractions, exponentiation, but you can use the built-in 25 kinds of mathematical functions (sin, cos, tan, arcsin, arccos, arctan, sinh, cosh , tanh, arcsinh, arccosh, arctanh, exp, pow, sqrt, ln, log, round, trunc, sng, abs, min, max, arrange, combine), you can use custom variables, custom functions and parameters for calculating cost per unit (currently only supports cm and angle in radians), to use the constant π, e participate in the calculation.

2. Using mathematical drawing board, you can replace the Ruler mapping, but you can make advanced image and function of the image trajectory, can dynamically change their properties, measure their relative value, you can create custom variables, custom functions, using natural mathematical formula input expression, beautiful, clear, inside it is built up to 25 common mathematical functions.

3. - Sketchpad provides fractional, radical, radical times, index, subscript, A superscripts arranged formula, C and superscripts combination formula, Σ summation formula, Π quadrature formula also provides Greece enter letters, overline formula (expressed segments), the arc formula (expressed arc) and other mathematical formula, the formula can be pre-cut, copy, paste, natural way to enter, the natural way to edit, and consistent operation iOS text edit.

4. - New Function: Create a mathematical function objects, custom functions, variables with other calculations.

5. Sketchpad is a set of mathematics dynamic geometry, mathematical computation, formulas input application.

6. All visual elements are displayed in a scrollable Sketchpad infinite area, Sketchpad area content can be permanently saved as a separate file.

7. Two finger swipe means you can scroll sketchpad content at any time.

8. - Ratio: the ratio of AB measure of three ABC / AC, unit 1.
