Ahh thank you, this makes a lot of sense now.

comment Taylor's theorem for $|x|<1$ for $\sqrt{1+x}$?
@Hurkyl so I can do a Taylor expansion at 0, and then show that the radius of convergence is 1?

comment Show that these groups are not cyclic and hence have no such generator?
Great thanks :) But if a group has length $n$ and order $n$ does that necessarily mean it's cyclic?

Oh, I think I understand the first one...for the second, it if because $C_2\times C_4$ has length 8 but order 4, so can't be cyclic?
