How to graph Taylor series on the Prime

The most complete port of Giac/Xcas on a calculator is the GPL port of KhiCAS available on the TI Nspire CX and CX II, with multi-precision float, arithmetic interval, all giac commands, and also MicroPython and the QuickJS Javascript engine. The CX version has an exam mode compatible with KhiCAS.
Then you will find the Numworks GPL port for unlocked Numworks N0110 calculators with OS version <=15.5 : it does not have quickJS support and most importantly the RAM capabilities are very limited (a little less than 128K of RAM). It is compatible with exam mode.
Then the HP Prime port of Xcas : this commercial port has some commands disabled and lacks some LGPL libraries (incompatible licenses). On the other hand, it is fully integrated with the system, exam mode (in countries allowing CAS) and has the best hardware ressources available on a calc.
And then you have the Casio ports for the Casio Prizm family (CG10, 20, 50) and for the B&W Fx-9750GIII, Fx-9860GIII. They are limited by the addin limit size (2M: I had to remove some commands and online help to fit) + RAM limitations (around 128K of RAM on the Prizm, less on the B&W Casio).
