Let $f(x,y)$ be a complex degree $d$ polynomial that has this particular form.
$$ f = \frac{f_{02}}{2} y^2 + \frac{f_{21}}{2} x^2 y + \frac{f_{12}}{2} x y^2 + \frac{f_{03}}{6} y^3 + \frac{f_{40}}{24} x^4+ \ldots $$
This polynomial $f$ can be thought of as an eleme... | {"url":"http://mathoverflow.net/questions/77130/closure-of-singular-points/77821","timestamp":"2014-04-21T02:46:26Z","content_type":null,"content_length":"73999","record_id":"<urn:uuid:9d8509e0-e273-4ad6-a1e9-bea397f54afa>","cc-path":"CC-MAIN-2014-15/segments/1397609539447.23/warc/CC-MAIN-20140416005219-00109-ip-10-147... |

We're looking at c = 2 and f(c) = f(2) = 4. We want this point to be in the center of the window, start by graphing f with
0 ≤ x ≤ 4
0 ≤ y ≤ 8.
We see this:
We want to have f(x) within 0.1 of f(c). Therefore we want to have f(x) within 0.1 of 4, or 3.9 ≤ f(x) ≤ 4.1.

Question about limits
In part (a) of my questions I'm asked to show $\lim_{n \rightarrow{\infty}}[\frac{1}{n-1}]^\frac{1}{n} = 1$
I have done this, and part (b) asks me to consider a sequence of functions
