Grafunc 1.3

Grafunc is a function plot application supporting multi-touch navigation and function value inspection.

Use it to visualize multiple functions at the same time and solve for roots, function intersections and min/max points.

The multi-touch interface makes it easy to move around and zoom in/out for closer inspection. You can use it in portrait or landscape modes.

Grafunc is a useful application for students, engineers and math enthusiasts.

ANSWERS TO REVIEWER ISSUES:

Dont forget to use the multiply operator *. For example the expression 3x^2-1 should be written as 3*x^2-1. And 2cos(x) as 2*cos(x).

The equation is always an equality to zero so to plot x^2+3x+1=0 just type x^2+3*x+1 (with multiply operator on 3x and no =0 at end).

For exponential functions like e^(x+1) type exp(x+1).
