First of all, hi mansi, how are you ?
Now, lets come to the business part
The question can be done as follows :
[ -1]
[0 ] [ x(x +1 +1) / { ln(x+1) } ]
[ -1]
[0 ] [ x(x +1) / { ln(x+1) } ] + [ -1]
[0 ] x / { ln(x+1) }
Now in both these parts, put t=x+1
So, x becomes t-1 and ln(x+1) can be substituted by et
Then use By parts and you'll have your answer.
Well, if you like the solution, i won't mind a salute !!!!!
