Calculus(圖1)-速報App

The app differentiates and integrates user given polynomial, that can also have fractional coefficients. The derivative and the integral can be fetched to be further edited. If the polynomial (also derivative and integral) doesn't fit to the screen, the polynomial can be scrolled. Any term of the polynomial can picked up to be edited by touching it for 1.5 seconds. The polynomial can also have a constant as a term.

In addition the app graphs the polynomial(s). There are two graph views.
