This is the first of several YouTube clips where Khan shows in nice detail how to work trig substitution.
This is part of
which is a wonderful collection of hundreds of YouTube clips showing most of the mathematical procedures up to college level Calculus.
Let me know if this was helpful

neither of these videos explain the situation where vaiable x is in the numerator, so i still cant solve it
