I published recently initial version 1.0 of a calculus program called Calculus to Android. I have plans to publish PC version too, when the program is developed further.
The program differentiates and integrates user given polynomial and simplifies all the fractions. The coefficients can be 4 digits long. I haven’t given a limit to amount of terms in the polynomial, the available memory is the only limit.
The coefficients can be fractional too — and of course negative or positive. Next version will be out soon, which will improve some features of the program and add some features too. I’m not aware of any actual bugs in the program at the moment.
See below a demonstration video of the program (in the video Calculus is compiled to PC and used with the mouse):
Calculus is free educational program.
Notice that when integrating the polynomial, Calculus doesn’t give the integral constant.
