The Attempt at a Solution
1st,i make u=x+1 ,so du/dx =1 du=dx..while i use /dv =/ln(x+1) dx and after integrating my v=1/(x+1) so subtitute into uv -/vdu but my ans turn out to be wrong so i need some guidance over here.i guess my integration for dv is wrong but i can't really see it..so could any1 please help me..thanks..
