Comment #1 on issue 1394 by [email protected]: integrate(x*sqrt(1+2*x),
x) can't do it yet
http://code.google.com/p/sympy/issues/detail?id=1394
Please see pull request #165.
I added integration by parts (with one condition) when everything else
which is present can't do the given integration. If the pull request in
added, SymPy will return -
In [1]: integrate(x*sqrt(1+2*x),x)
Out[1]:
3/2 5/2
x⋅(1 + 2⋅x) (1 + 2⋅x)
────────────── - ────────────
3 15
There are currently two failed test with this, but one is from master
branch itself and other is not serious.
