ParametricFunc app for iPhone and iPad

Displays and analyzes functions of type "f(x)" (in 2D), "f(x,y)" (in 3D) and "( x(k) | y(k) | z(k) )" (in 3D) with 0 (cylindric and cartesian coordinates are supported).

A slider and a clock button allow the user to dynamically change parameter t in a previously set range.

The curve of max./min. points for functions of type "f(x,t)" is stored in memory for optional display.

Implemented are pinch-support for zooming in and out with 2 fingers , one-finger perspective change (for 3D functions), a function value table for f(x) , a 5 position function memory (f1 to f5) as well as 4 predefined sample functions for the 3 available function types.
