I get a complex answer in CAS, an invalid input message in HOME. Physical software version 7820, and same behavior on iPad emulator.

Can someone tell me why?
Try this:
∫(ln(2+sin(x)),x,3.0,5)
Note the 3 is typed 3.0 not just 3
Then you get about 0.555 for an approx answer. It's an approx/exact issue.

Hi!, all:
If configure HP PRIME, for CAS and in CAS Setting in Approximate mode, Standar mode with 12 digits, the result is ... 0.555085197181
In Plot, if any value, of function is <=0, the result is NaN (Not an Number).
See, the attachment's in HP PRIME and Wolfram Alpha.
