I feel so
doing this problem.
PLEASE HELP!!!! AND TEACH ME How TO DO IT.
My question is this.
use the substitution x=2tan(y)
(37dx)/(x^2*sqrt(x^2+4))
give the answer in terms of y.
I did the substition, but it looked more complicated.
It doesn't look like a u*du thing, but it does look like some arcsin thing... i couldn't figure it out. The x^2 is bugging me.
PLease help!!!
