1. ## HOW DO I DO THIS QUESTION: Integration

So recently while reading BNHA Manga, I realise this question:

Integration of (0 to ln(1+sqrt2))((e^x-e^-x)/2)^3 . ((e^x+e^-x)/2)^11

No clue pls help! Amswer 107/24
Thank you in advance  Reply With Quote

LOL, Ths is from the januray issue. i remeber i was tryna figure it out too LOL
i asked my teacher and he did it fir me

Carrying on wat integrand said,

sinh^-1x is ln(1+sqrt(x^2+1))

if u put 1 as x then its the same as ln|1+sqrt(2)|

and sinh(sin^-1(1))=1

simplifies it a lot

if u need the wrking out i can do it fir u  Reply With Quote
