Xcas/Giac vs HP Prime: LambertW

[rprosperi]

Xcas/Giac has many functions and capabilities that are not available in Prime (for lots of reasons, including some obvious ones like needed resources, UI limitations, etc.) however there is no definitive list of what is/isn't included in Prime, partly because Xcas/Giac continues to evolve and add capabilities and to a lesser extent, Prime has also added more in nearly every software update (roughly twice per year), so any list would be misleading or obsolete.
