 Apr 16 comment Why doesn't this definition of natural numbers hold up in axiomatic set theory? @MartinArgerami I've personally seen very few issues with the mathematical articles on Wikipedia (other topics notwithstanding). You'll find mistakes and typos in any reference. I've seen mathematics textbooks that are full of typos (and unlike Wikipedia it's impossible for them to be fixed once the book is printed).

Wikipedia is a great place to learn mathematics. Mar 25 asked Can the Monty Hall paradox be explained by Berkson's paradox?

Feb 26 comment “If everyone in front of you is bald, then you're bald.” Does this logically mean that the first person is bald? @DanielV ah yes, you are right. Feb 24 comment “If everyone in front of you is bald, then you're bald.” Does this logically mean that the first person is bald? @DanielV it's strong induction without the base case. Jan 6 awarded Nice Question Nov 19 answered Are there any limit questions which are easier to solve using methods other than l'Hopital's Rule? Nov 19 comment Are there any limit questions which are easier to solve using methods other than l'Hopital's Rule? It probably goes without saying that it's a poor choice for expressions that aren't in an indeterminate form ($\frac{0}{0}$, $\frac{\infty}{\infty}$, $0\cdot \infty$, $0^0$, etc.). Nov 19 comment Are there any limit questions which are easier to solve using methods other than l'Hopital's Rule? $$\lim_{x\to \infty}\frac{2^x}{3^x}$$ is even simpler.

Nov 14 comment Proof that if $x,z > 0,\ x+z < 1,\ (1+x)\times (1+z) \leq \frac{1}{(1-(x+z))}$ I'm guessing $z=y$. Nov 5 awarded Good Question Oct 20 comment Is there an algorithm for deciding big/little-O queries? Why $\log^{0.999}n$? Oct 20 comment When solving for eigenvector, when do you have to check every equation? I don't think it makes sense to say "not all the equations in (3) are linearly independent". Linear independence is a property of a whole set, not of the elements of a set. It would be clearer to say "the equations in (3) are linearly dependent".
