This little application will calculate derivatives and integrals of decimal number polynomial functions according to the power rule. The application uses JOptionPane dialogs for input/output. As shown in the demonstration, the application accepts some implicit and unsimplified forms of polynomials.

To use the Derivative and Integral Calculator, simply execute the jar file included in release v1.0.

If you want to take a look at the code, all of the code is included in the repository's source_code folder.

There are plenty of superior online resources for computing derivatives and integrals. The reason why I wanted to make this script was to better understand how to apply the power rule. However, the vast majority of time spent making this ended up going into converting String to Polynomial and vice versa (The Polynomial constructor and toString method).
