System Architect / Senior Software Developer in Calgary, Alberta. Consulting on various projects, mostly with a .Net or classic ASP background. I've been developing Web applications and Websites for over a decade now ranging from using a propietary markup and ISAPI extensions(C/C++) to Classic ASP(VBScript) to ASP.Net(C# 1.0/1.1/2.0/3.5/4.0/MVC) I enjoy solving puzzles such as Sudoku and mysteries. My previous work involves using various Agile practices,e.g. Scrum and pair-programming, on a CMS project within an IS department's web development group.

I enjoy sharing what I've experienced, learned or think may be worth sharing with the world.

comment Can I demonstrate that this final sum is natural number?
Are you familiar with en.wikipedia.org/wiki/Exponential_function ? That sum is $e$ which isn't natural or rational actually.

comment Number of ways to place exactly two kings in each column such that no king attacks another
What if n is really small like 1 or 2? Are there still that many possibilities if $n$ is really small?

comment Sum of odd numbers is odd if each of the natural numbers is odd
Expand that expression and note that it ends in a "+1" with the rest having 2 as a factor.

comment What is $\frac{9}{3} - \frac{1}{2}$?
3.0-.5=2.5 in my world of decimals. 2.5 would also be 2 and a half or 5 halves.

comment Please explain counting; Discrete Structures
Wouldn't this be overcounting since there is only 1 vowel and not multiple ones?

comment Irrational numbers in between $n$ and $n+1$
Yes though consider whether you'd think the size of this set is countable or uncountable.

comment How to show $a c\equiv bc\pmod{n}$ where $n \ge 2$ does not imply $a \equiv b \pmod n$?
@idm, note that in your example c is congruent to 0 mod m.

comment Two definitions - do they differ?
Note that the expression in brackets is a subset of the initial sequence and thus there could be other terms that don't follow this rule while the second statement is a bit stronger than the first.

comment How to prove that $\lim_{n\to\infty}{|\sin n|}$ doesn't exist
The original function is the absolute value of sin, please fix your answer for the function asked.

comment Prove that $ 2^n \not \equiv 1 \pmod{n} $ for any $n > 1$.
Note for $n=1$ the initial statement does hold for 1 dividing anything.
