can the prime really not solve this integral?

Can you reliably reproduce the hang?

Yes - both hang at "calculating" for me 0--> any positive number. On Symb to reset. Dont know if related to CAS settings pg 2: 10, 1, 100, 1E-12, 1E15 and 40 in order or something else.

Also noted that in CAS, integrating 0 to say >1500 starts giving "adaptive method failure, will try with Romberg..." error. Integrating 0--> <1500 gives 6.49 approximation.

I've just tried it here on a device with the CAS settings above (with 1E-15 for the "Probability" setting), but a numerical approximation simply came up quickly. What firmware are you using? Does it occur with default factory settings on your device? To be sure we're looking at the same function, would it be convenient / possible for you to post a photo of the SYMB view?
