Yep! Hint: I like to use a small spacer: \, in the $\LaTeX$ code to get spaces after $f(x,y)$ and in-between the differentials. I think it looks...

Unfortunately, your inequality is the wrong way round. It should say $\dfrac n{\sqrt{n^3+n}} \geq \dfrac n{n^3+n}$ (as the denominator gets larger,...

I think, then, that you will have to break up the integral into three pieces, because the rule of association changes as you go. The problem is that...

Are you trying to calculate $P(|X+Y|<0.5)$ or $P(|X-Y|<0.5)?$ If the first, then your plot would seem to be incorrect. Here is W|A's plot command:...

Congratulations to Opalg for his (incredibly concise and, of course, correct) answer, which follows: In the identity $(a*b)*a = b$, substitute...

Because if you move a vector around, keeping its length and direction the same, you have not changed the vector. The vector $M-P$ is precisely the...

This translation isn't quite right. You need to move the point $(10,11)$ thus: $\displaystyle (10,11) \to (10,11) - (-1,-1) \to (11, 12)$. So you...

That's not a problem. The empty set is a subset of every set. So even if $G = \emptyset$, it's still true that $G\subseteq \Bbb{N}$.

The definition of $G$ is of the form $G = \{z\in \Bbb{N} \mid \ldots \}$. This says that each element $z$ of $G$ is an element of $\Bbb{N}$, in other...

The line CP has gradient $\dfrac{p_2-y_0}{p_1-x_0}$. The line $AB$ is perpendicular to this, so it has gradient $-\dfrac{p_1-x_0}{p_2-y_0}$, and its...

7. Why play safe? Aren't you living in a free country?
8. I don't know (yet) if I've got something worth posting, but I have a comment on your last sentence.

Two things about hoping to not offend:
1. It would be rediculous to be offended, and besides somebody, inevitably, is likely to be "offended".
2. (reasonale ) Opinions are not meant to offend. By contrast, in science "offending" is not relevant.
So why should it be different when it comes to religulous matters?
