Here you can see past changes of the room topic. Certainly there are rooms where room topic has been changed more often, for example, Calculus & Analysis.
I read on the internet about how discrete Fourier transform works. Based on that, I made up these formulas. A discrete function $g(t)$ takes $N$ values at equally spaced intervals between $t=a$ and $t=b$. $g(a)=g(b)$. Now, the values of the function at $a, a+\frac{b-a}{N}, a+\frac{2(b-a)}{N},.......
room topic changed to Modern Abstract Analysis: For functional analysis, measure theory, and related areas. MathJax in chat: math.ucla.edu/~robjohn/math/mathjax.html [functional-analysis,] [measure-theory,] [real-analysis]
