if u can find any mistake till this step please help me out
- post solution if u have..
Even I had come till the second step. No, I don't have solution for this.
a option for sure correct please see its e^(-x)
instead of e^x at ln(..) in this term..
answer key pointing wrong answer..
Could be... Let's ask @Shwetanshu_2018 bhaiya...
I got 'c'. Posting in a minute.
ooo sheesh i got my mistake @Samarth_2020
its should be 2ln3 instead of ln3 now c option is correct i apologise for my mistake..
Your method is far better btw.
I don’t think ,integration of 1/( e^x + 1 ) can be written as ln (e^x + 1)
For integrating this you need to split numerator into e^x +1 -e^x
sir multiplied nd divide by e^(-x) then taken t to it.. @Shwetanshu_2018 bro will turn sane result..
That will result in
-ln (e^-x + 1 )
But you have written
-ln(e^x + 1)
sir i apologised for it in #post7
