You better prove that. I could have said that your function is less than and you still would have believed me.
lol man you are right, when I first saw your answer I did mistakenly thought of it as a correct one cause I thought that the numerator was "1" , but instead it was "x" . (I suppose the same thing did happen to you too?)
So I think that its not correct, because for n=1 (and lets say x=2)
As far as mentioning do we get this from a Taylor Series?
