Question

Not so sure what to do....
integral of (1-sqrt(x))/(1+sqrt(x))

Answer 1

yeah it does

Answer 2

atm we've gone over u-sub. Not quite into trig sub nor integ. by parts.

Answer 3

I'm sorry I was waiting for you to finish. But, I a bit confused as to how you balanced du and dx.

Answer 4

u=sqrtx
du/dx=1/2 x^-(1/2)
so du=1/2 x^-(1/2) dx

Answer 5

redoing it from here

Answer 6

do u follow so far?

Answer 7

yes, except as to where you got that 1/2 in the final part

Answer 8

\[put \sqrt{x}=u,x=u ^{2},dx=2u~du\]
