Graphical Calculator for the iPhone or iPod Touch

This free app is only going to be required by a select minority, if you’re into any type of maths studies then surely a graphical calculator is a must.  To save you buying a dedicated expensive device you can get this for free to help you. Obviously you need an iPhone or iPod Touch though…

You can enter in four different equations with a range of options; so not just a simple y=4x graph. As well as displaying these equations graphically you can also see where they meet and the x,y co-ordinates of the relevant equations.  It may sound like a foreign language to you but it will definitely make mathematics easier.
