    how do i integrate this??

    how do i integrate this function?


    i have tried all the methods i know and havent cracked it, the best try i have had so far is


    ===>t=ex; dt=exdx


    now from here i tried integration in parts and got really complicated




    how else can i solve this

    Use the substitution t=sqrt(exp(x)-1) => x=ln(t^2+1)
