There are engineering professors who believe in mathematical rigor. They're a minority, but they're out there. I've had classes with a few and it's like a breath of fresh air every time

>>8756447
well, it passes the vertical line test.
can be represented piecewise.

>>8756888
It has a non-zero integral and thus is not a function

>>8756900
what the fuck are you talking about?

>>8756919
>From a purely mathematical viewpoint, the Dirac delta is not strictly a function, because any extended-real function that is equal to zero everywhere but a single point must have total integral zero

>>8756888
It doesn't really pass the vertical line test because its value is infinity at 0

>>8756957
but it maps zero to one and only one value
>but infinity is not a value
then it is discontinuous at zero, but functions need not be continuous

Yeah no. There are perfectly rigorous extensions of the notion of function that include the Dirac delta and related.

Your prof is probably just using a shorthand for this information which he well knows.

The OP post is on the same level as "how can 0.99* == 1?" by someone who doesn't understand how the real numbers are put together (as equivalence classes of Cauchy convergent sequences or the equivalent).

>>8758141
The sum of the euros is not the sum as the sum of the euros times delta x, spergo.

How many times are you going to make this thread matey?

I don't really understand this. Isn't function used interchangeably with map? The delta function is a function that maps other functions from certain function spaces to numbers. Why would the term "function" only refer to functions from numbers to numbers?

>>8757131
I should have replied to OP not to you.

Man!!! you think that's a joke. Look at the government's program for recruiting STEM talent.

You some dumb fuck with a degree who will keep your head down? You're hired.

You an actual productive scientist in an age of miserably low scientific productivity? Fuck off, you can't have freedom and a job buddy.

Please see the following posts. It's only non-zero at one point and thus must have a zero integral
