Can anyone give me any advice on solving this integral?
((x^2-1))/((square root(2x-1))
Would I use u=x^2-1 then du=2x ?
It's often easier to pick your sub as what's in the square root as this gives the nicer when it comes to integrating.
For the first term sub and also
This gives a first term of
When that's integrated we get
where which is the constant of integration.
Can you integrate the second term using the same u-sub
