    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

    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
