#184 Incomplete result for integrate(log(x+sqrt(1+x^2)),x)

[pagingzhu]

Should I report a bug here? I can't find a place to report a bug.
the code:

(%i1) integrate(log(x+sqrt(1+x^2)),x);
(%o1) x*log(x + sqrt(x^2 + 1)) - x + arctan(x) - integrate(x/(x^3 + (x^2 + 1)^(3/2) + x), x)
(%i2) integrate(asinh(x),x);
(%o2)                      x asinh(x) - sqrt(x^2 + 1)

As asinh(x)==log(x+sqrt(1+x^2)), why maxima was not able to finish the integration in %i1?I've modified the output to plain text format in a single line.

The Version of my maxima:
Maxima 5.30.0 http://maxima.sourceforge.net
using Lisp GNU Common Lisp (GCL) GCL 2.6.7 (a.k.a. GCL)

It seems that I have found the right place.

I've moved this ticket to feature-requests since it doesn't appear to be a bug, just an incomplete result. I tried it with a recent build and the result is the same as before.
