How to invoke ejss library for analytical solution for derivatives?

Hi prof Paco and Wolfgang,

How to invoke ejss library for analytical solution for derivatives?

I am trying to re create tracker's modeling capability for analytical solutions.

For example if analytical function is
X= At^2 + Bt +C

The derivative would be
Velocity= 2Ax + B

And again
Acceleration= 2A

My source code is here

Thank you.

Computing symbolic derivates using a mathematical function expressed as a string requires computer (symbolic) algebra capabilities and EjsS does not support computer algebra.  It is, however, not difficult to import an external jar file file (when creating Java programs) or a JavaScript library into EjsS if you find a code library that has features not included in EjsS.  Add that library to the User File field in the Information Dialog to include it in the compiled package.

Dear Prof Wolfgang,

thank you for the reply.

i google and found this

https://dev.geogebra.org/trac/wiki/SourcesForUsedLibraries

it is a GeoGebra used Library, and i know GeoGeBra has the computer (symbolic) algebra capabilities that i wish to inject into my EJSS simulations.

is there an example of usage of external JavaScript Libraries on OSP yet so that i can try to figure out how to add code library!

thanks!

my attempt to test it on GeoGebra

The Bound Eigenstate Superposition JavaScript model imports three JavaScript files to compute harmonic oscillator wave functions using Hermite polynomials.  These files are in the jslib subdirectory of the source code archive for the following model.
