So I'm a little confused about the difference between iterated and double integrals, I did a little bit of looking around on the internet, but I couldn't find anything to answer my question. On Wikipedia, there's something about area vs numerical computation, but it was really hard to understand the article. Could someone please explain this to me?
Double integrals are integrals of function of two variables, but Iterated integrals are integral of integral... of single variable function.
Example $$ \iint f(x,y) dx dy $$ is a double integral but $$ \int \Biggr ( \int f(x) dx\Biggl) dx$$ is an iterated integral.
