Lower boundary = 2sqrt2
upper boundary = 4
(sqrt(x^2 - 4)) / x
So far i've set x = 2 sectheta
dx = 2 (sec theta) (tan theta)
From here i'm having problems what I should do next
I know I have to place new boundaries.
The new lower boundary is gonna pi / 4
the upper boundary i'm having trouble figuring out. what is the sec theta when it equals 2?
