RE: Promblem with integration

This is an endless quest and I'm not convinced it is really usefull. My programming time is finite, I have to make choices, Fresnel integrals are not on the top list. I apologise if I reopen this post, but after a bit of time I wonder if there are some developments or thoughts about the implementation of Fresnel integrals S(x) and C(x) and erfi() in CAS (in the Prime) or if there is already any custom program (or App) to handle them simply and friendly. Thank you! Salvo EDIT: could it be so simple? There are warnings with the below code, therefore I'm wondering... Code: #cas Code: EXPORT Fresnel_S(x) ∫aL√0mic (IT9CLU) :: HP Prime 50g 41CX 71b 42s 39s 35s 12C 15C - DM42, DM41X - WP34s Prime Soft. Lib |
