How to decompose the given function into several peaked functions like Gaussian or Lorentzian?
During applied mathematics, I am wondering how to decompose the data $[x,y]$ into several elliptic-shaped functions, namely
$$f[x,y]= H \cdot \left( 1 + \bigl( \frac{x-x_1}{a_1} \bigr)^2 + \bigl( \...

Volume of Revolution $f(x) = x^2$
Suppose you are given $y = f(x)$
I want to use double integrals, instead of the traditional washers.
Suppose even better, $f(x) = x^2$
Find the volume of $f(x) = x^2$, $x = 0$, $x = 4$, $y = 0$ &...

What is a simple example of a limit in the real world?
This morning, I read Wikipedia's informal definition of a limit:
Informally, a function f assigns an output $f(x)$ to every input $x$. The
function has a limit $L$ at an input $p$ if $f(x)$ is "...
