Hello,
the initial version 1.0 of my Calculus program is now on Google Play.
The program differentiates and integrates given polynomial. Fractions are simplified.
Below a video of the app:
Looks very good.
Thanks, it works well too.
Version 1.1 beta of Calculus published.
What’s new:- Two changes in GUI: Only one button for minus and plus, added “backspace” button for editing.
- While editing the 4 digits of the exponent always fit to the screen
- Also the derivative can be fetched to be further edited
Edit: I almost forgot, the testing link: https://play.google.com/apps/testing/com.poly.calculus
I got the test ads working with this app, but the real ads don’t show up on my Android devices. All I changed was the IDs of the ads. Still, on Play Console in Google’s test pictures the ads seem to show up. Is there a kind soul who would test at least, that do the ads work..
Version 1.2 available on Google Play. Link.
What’s new:
- any term of the polynomial can be picked up to be edited by touching
- editing of the term improved
I’ve been very passionate with my calculus app, version 1.3 already available. Same link as above.
What’s new:
- an UNDO button added
Ads are working on my acer jade.
Good to know that the ads are working.
I’ve been working really hard on this app. I published today version 2.0 beta, that also graphs the polynomial(s).
The app can also be used just to graph functions.
Calculus is now at version 2.2 beta.
What’s new:
- Graphing of the polynomials improved
- Missing features of editing a constant added
- While scrolling the polynomial, picking up a term works better
Calculus v2.8 beta available. https://play.google.com/store/apps/details?id=com.poly.calculus
Feature advice – to show marker (like blink cursor) at the tapped place on screen to see where we going to insert digits/symbols.
I try to implement that to the next version — very good idea, the user sees better what’s he/she is doing.
Calculus is now at version 2.9.7. Two graph views. The original has been a little improved, the second tries to fit any curve(s) to the screen. The calculation precision is the limit.
Very cool!
