Automatic even/odd splitting
Statement of the Problem
Suppose you have a real valued function on the reals, say f. We can split it into the sum of an even and odd part:
f(x) = f[odd](x)+f[even](x)
f[odd](x) = (f(x)-f(-x))/2, f[even](x) = (f(x)+f(-x))/2
If f
has a power series around zero, then all of its terms ... | {"url":"http://blog.sigfpe.com/2010/09/automatic-evenodd-splitting.html","timestamp":"2014-04-18T02:57:49Z","content_type":null,"content_length":"59769","record_id":"<urn:uuid:90d61ac0-6d11-4440-8da2-4a5f750adb12>","cc-path":"CC-MAIN-2014-15/segments/1397609532480.36/warc/CC-MAIN-20140416005212-00646-ip-10-147-4-33.ec2... |

How old are Kendall and Zack?
I remember someone saying he (Zack) was young (16 or 18) when Ethan was born.
Thorsten is 40, born in 1966.
If Ethan was playing 25 when he died earlier this year and dad was 17 when he was born thats 25+17=42.
So he's probally playing btwn 41 years old and 44 years old.

The Sierpinski-Knopp Curve
As a last example of using a continuum of IFS's to get a sequence of fractal curves that converges to a planar space-filling curve, we return to the Sierpinski-Knopp curve that was described as the

Fredholm operator
Fredholm operator
A Fredholm operator is a bounded operator between Banach spaces that has a finite dimensional kernel and cokernel (and closed range). Equivalently, it is invertible modulo compact operators. That is,

Introduction to Derivatives
Re: Introduction to Derivatives
Ah, but MathIsFun, what if Δx was 0? Then it must be that Δf(x) is also 0, no matter what the function. So the question we are asking is "What is the slope of a single point of any function?" if we
consider Δf(x)/Δx.
