Unfortunately, you have apparently already decided that "the conjugate is no help" and that is certainly the method I would suggest! It also helps to know the basic limit, .

Or, just calculating that quantity for, say x= 0.00001 should give you a good idea. - Oct 11th 2012, 01:16 PMpnfullerRe: limit help
