Integral hangs the physical Prime

[C.Ret]

Thanks parisse for this input.

This explains the mystery around the strange way to rewrite expressions and why different versions of CAS reorder expressions differently as point out by Albert Chan.

I take this opportunity to salute the work done to produce this extraordinary calculator. I still have so much fun using it. Whether it is to do a little math or to express graphical and statistical results. Pleasure all the more since the last update, I have not encountered any crashes of the calculator or disconnections of the Connectivity Kit.

That's why I wanted to respond to Irdheat, because its integration does not cause any problems on my machine.

By the way, to prepare the answers above, everything worked well and I was able to further explore this incredible machine.
And the last screen capture, obtained without a warning message, allowed me to understand what is happening and to have rigorous answers to my questions.
It is true that analysis is not my privileged domain, I am a bit out of my garden here.

Once again, thanks to the entire team that produces and maintains the HP Prime at its best level.
