Any good app for an Economist?

[Theros]

Hello, im starting my semester in the university (btw im studying Economics) but im searching for an app (iPad or OS X) that can graph, specially for my course of Microeconomics (and next years Macroeconomics).

The problem is that i don't know any good one, anyone can recommend me one if is possible, that can give me details (Income, Elasticity, Equilibrium price, etc.) with formulas for verification of problems?

Thanks
