Thanks Micromass and HallsofIvy for your replies :)
I began the problem by distributing the 1/ε term. So, what I had looked a bit messy. I'm surprised I didn't notice to use the conjugate of the numerator...so use to looking in the denominator. Problem solved :)
Thanks again.
I've been playing around with a free PDF Calculus book lately. But, I have no way to check the logic used to get to a particular answer. I've been trying to find the standard part for:
(1/ɛ)((1/sqrt(4+ɛ))-(1/2))
I've tried every way I could think of to algebraically manipulate this in...
