Grafunc
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:
To use the inspection modes, click with one finger and hold for 1 sec before moving (like when moving the cursor through a text field).
Don't 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)'.
What's new
- Faster function sampling and drawing.
- Functions with errors shown in red text while typing. Only correct (black text) functions will be plotted.
- Updated to OS 3.0
