Calculus has jumped from version 1.3 to version 2.0 as graphing the polynomials is included in the app. The app can also be used just for graphing polynomial functions.
Calculus is an Android app that differentiates and integrates user given polynomial.
The polynomial can have negative and positive fractional coefficients too.
A term from the polynomial can be fetched to be edited by touching for 3 seconds at the term.
To edit a fractional coefficient, tap at first below the X, then tap below or above the line to enter denominator and numerator. To switch to back integer coefficient, tap again below the X. Fractions are always simplified.
If the polynomial doesn’t fit to the screen it can be scrolled.
The derivative and the integral can be fetched to be edited by touching at them for 3 seconds. Notice that this version doesn’t give the integral constant when integrated. This is worth noticing, if you wan’t see real results to the original polynomial in further integrations.
Also a constant can be given. This is can be done by touching somewhere in the term editing area for 3 seconds. Back to editing a coefficient, touch for 3 seconds somewhere in the term editing area.

I’ve plans to develop this program further and publish also a version for PC. Probably after next update I will create a new video for the app.
