[Announce] Integral, Derivative, Limit and SymPy for Sailfish
 

Some releases of mathematical and programming tools for Sailfish :

- Integral calculates mathematical integrals :

- Derivative calculates mathematical derivatives :

- Limit calculates mathematical limits :

- SymPy is a computer algebra system (CAS) written in pure Python, it has both Python 2.7 version and Python 3 version at OpenRepos.net :

IPython 2.2.0 (only for Python 2.7 at the moment) is also available for Sailfish, see the topic "IPython (terminal, Notebook) for Sailfish".

Re: [Announce] Integral, Limit and SymPy for Sailfish
 

I've tested Integral and Limit only on Sailfish SDk emulator, Sailfish @ N9 and Sailfish @ Nexus 4, as I live in Brazil and don't have a Jolla smartphone.

Could anybody with a real Jolla smartphone just tell how much time in seconds Integral and Limit take to load SymPy ? It is shown in the starting screen. Please give the time for first start, then close the app, then the time for 2nd start.

Also, while rotating the Jolla smartphone, will Integral and Limit remain in portrait mode ?

Re: [Announce] Integral, Limit and SymPy for Sailfish
 

Here are some results.

Integral: 3.63 s. then 3.42 s.
Limit:3.39 s. then 3.37 s. (additional tests give values around 3.4 s.).

Maybe I should have restarted the phone before testing the second program.

And yes, they stay in portrait.

Derivative for Sailfish is now released.

Thank you for this series, it is very much appreciated.

Any plans for differential equations? Those would be especially useful for myself.

EDIT: More info here.

My current plan is :
- release new versions of Limit, Derivative and Integral for Sailfish with some new features (zoom for result, save settings, cover info and actions, etc);
- release Limit, Integral and Derivative for MeeGo Harmattan (in this order), with more and more features. I've tried to create "Calculus" with their features, but it became too complex in terms of GUI (for the user) and development;
- maybe MathPlot, a Qt Quick GUI using MatPlotLib/NumPy to plot many types of 2D and 3D graphics. For MeeGo Harmattan and Sailfish.

Afterwards, there are many possible applications using SymPy, MatPlotLib, NumPy, Uncertainties, etc. Including your suggestion.
