Using the substitution you'll obtain an easy integral (rational on ) .
I'm trying to find the indefinite integral of:
(root)(x) / (root)(x) - 3 , the -3 is not under the root-sign
I've tried various u-subsitutions, none of which have made the problem any easier. I also tried using polynomial division to simplify the expression to
1 + ( 3 / ((root)(x) - 3), which I still cannot solve.
Would appreciate any help!
