Joel said there was an example of little o in the textbook, on pg. 191.
I haven't checked myself, but...

When I looked at the example in the book it didn't make little-o notation any clearer, the way the text presents it seems to be completly different than the way it was taught in class. From what I understand o(xn) just means terms of order > n , in other words lim(x->0) (o(xn)/ xn) = 0 . However I doubt that makes things any more clear.

For the little-0 notation, the answers I got were
i) 12 ii) 1
But they were done pretty quickly..

JebusMeany Ive done (i) and also got 12, i havent done (ii) yet
This problem set is evil, god i thought we would keep getting problem sets which would reuire easy computation, but i guess back to using your head it is.

I don't know either since I haven't gone to class. The only thing said was by the TA and he was being instructed by a student on how to do it. I got 12, ... how bout -6 for the other one?
for your 1? is it possible you didn't see that the bottom 1/4! factorial, and the top was 1/4 or something?

Um... although I put down 6 for the second answer as well, I'd just like to caution everyone that the polynomial expansion that we're using is for ln(x+1) and not ln(x), and that we don't really have an expansion for ln(x). And according to this, this limit approaches infinity. I'm assuming, however, that they made a typo and actually meant ln(x+1) since the polynomials cancel out nicely
