Statistics tell us that iPhone is mostly used by people in 18 to 25 age range. Basu=ically it means they are students. That’s why Grafunc that allows you to draw graphs will always come in handy.
Even if you are taken by surprise by a sudden exam you’ll remember that x-squared graph is a parabola if you have your iPhone and a couple bucks on your iTunes account..
Main window:
As you can see, the program allows you to simultaneously draw more than one graph (up to 6). You can assign different colors.
With standard moves you can scroll around and zoom. At high level zoom you’ll see the grid which allows you to position a certain point of the graph. You can also use “point by point” method to navigate. Just tap the screen and hold for one second to activate it. To turn it off, you need to do the same.
If you are looking for intersections with OX, minimums and maximums, graphs intersections points, you need to press Root, Min, Max and Intersect on the bottom panel accordingly.
The program features settings menu where you can slightly modify the interface. You’ll also find “Help” button there, which will tell you about available operations and functions.
At first launch, a window with tips will pop-up. I advise you read them all before you start.
The support of full-screen and landscape modes makes a nice surprise.
This program is worth the money spent. Very useful for all scholars.
The price: $1.99
