Physicists need to go.

How many times do we need this shit thread?

It's not a function, you dumbass. It's a probability space on [math]\mathbb{R}[/math] with all the measure concentrated at one point.

>>8442821
It's a tempered distribution, an element of the dual space of the Schwartz functions. Thus it is a function mapping S(R) to R. Take a PDE class.

>it's not a function

then why does it map every element from it's domain to a single element in its co domain?

Fucking retard

>>8442881
That's not how it's defined you dickweed

I bet you're American from how ignorant you are

>>8442881
It is undefined at x=0

Saying it's infinity at x=0 is an engineering approximation

>>8442824
okaay, you're right.
But PDE? It's a functional analysis, isn't it.

>>8442890
it's undefined everywhere because it's not a function

You understand your greenest is equivalent to "there's no function which lacks a continuous derivative of order n" right?
