You can put this solution on YOUR website!
int%28xlnxsinx%2Cdx%29.
Use IBP. Let u = lnx, dv = xsinxdx

===> du = dx/x and v = -xcosx + sinx (which you can also get through IBP).
===>

= .

Next time, if you want to do integration of functions, try Wolfram Alpha or Symbolab first.

You'll get a faster answer and solution there than you can type your question here.
