iCalculus

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:

sin(x), cos(x), tan(x), log(x) (the same as log(x)10), log(x)2, ln(x)(the natural logarithm), exp(x) (the same as e to the power of x), sqrt(x), asin(x), acos(x), atan(x), sinh(x), cosh(x), tanh(x), acosh(x), asinh(x), atanh(x), x^y (the same as x to the power of y).

This new version is expanding to financial calculus too. So if you need to do some boring and time taking financial stuff, just put the numbers and let us do it.

-New interface;
-Financial Calculus Mode:
-American Amortization System;
-French Amortization System;
-Constant Amortization System;
