iCalculus app for iPhone and iPad

This app is made for Engineering and Financial purposes, for all students, scientists and Math fans and who ever thinks this can come in handy some time.

You can use it to:

-Solve a ordinary differential equation system (up to 5 equations simultaneously), visualize the graphical solution for each variable, and send the solution data to an e-mail address.

-Find the value of a definite Integral using the Simpson method, and visualize the graph.

-Find all roots of a Polynomial equation (up to 11º degree).

-Find the roots of any real-valued equation using the Newton method (also called the Newton-Raphson method).

-Solve a system of linear equations using the Gauss-Jordan method (up to 5 equations).

- Use it to do some financial operations like Constant, French and American amortization systems.

List of supported functions:
