iDifferentiate app for iPhone and iPad

* build function and derivative graphs for select math and real-world functions
* including freefall, kinetic energy, probability density
* graphically solve equations, animate parameter changes
* learn about partial derivatives

Best on iPad, but works on iPhone/iPod too.

iDifferentiate is a fun interactive way of learning about various functions, their first and second order derivatives. With iDifferentiate you can calculate the dynamics of a freefall, compare the energy of a running train to the enegry of a rocket launch or learn how air pressure changes with altitude. You can also study examples of probability distributions and financial models. Youll understand the concept of derivatives and partial derivatives applied to real-world situations.
