comment If the integral $\int_0^\infty xf(x)\,dx$ converges, so does $\sum_{n=1}^{\infty}\int_0^{\infty}f(x+n)\, dx$
What have you tried? Please show your work.

And it took a fields medalist two years to solve...

comment Riemann Hypothesis Proof - legit?
What's inconceivable is the amount of time the author wasted, whether consciously or not.

comment Area between the graph of each function and the x-axis
You divided $(1)$ in four parts, but notice how some of the integrals yield negative values.

comment The question about the word of “Mathematics”.
No English word other than "mathematics" is an anagram of "mathematics."

He must have made that term up.

comment Project Euler's Problem Number 88
It sped up the program significantly, but it wasn't enough. I ended up opting for memoization, which worked.

comment Project Euler's Problem Number 88
@WillJagy I was going to ask this question at stackoverflow.com but felt it was more mathematically-inclined. I understand the problem and have theoretically solved it, but due to our current lack of computing power, I thought someone could perhaps point me toward a heuristic or a better idea.

comment If $A=\{1,2\}, B=\{1,2\}$, what is $A \cup B$?
Is this kind of question allowed here? It is misleading, and its resolution lies in book definitions the author could have easily looked up.

comment How should I begin when trying to determine a proposition whose truth value is unknown?
Don't think of mathematics as having some sort of rule book, but pure logic instead. Things need to make sense before you proceed!
