comment Examples of results failing in higher dimensions
Proof by pictures still exists in higher math, for example see: en.wikipedia.org/wiki/Commutative_diagram . Although I agree that at the very least there is a rigor behind them.

comment Finding $\csc$ with $\cot$
@Adam trig functions represent relations between the sides of a right triangle. Excepting some corner cases (like $\theta = \frac{\pi}{2}$) you can always construct a right triangle that "represents" the trig relation.

comment Finding $\csc$ with $\cot$
@Adam as I pointed out in my comment, even though you checked 12 times you missed the clear arithmetic error

comment Trig test review
FML is a fairly common adolescent phrase now-a-days, it wasn't meant to be offensive, but I agree it was unnecessary in the question.

You did everthing right, but 9+16 = 25 not 27

@Theo thanks for that, its what I get for working in a lab with a bunch of Russians - "gord-on"

comment Number of occurrences of the digit 1 in the numbers from 0 to n
While this is a correct way to approach this particular question, the actual problem in question (which is a project Euler problem) requires the sum total of all numbers that satisfy this condition for all digits 1-10. Not so easy (or fast) do with this brute force method (where do you set the upper search limit for instance?).

comment Number of occurrences of the digit 1 in the numbers from 0 to n
This is a not-so-veiled attempt to elicit a solution to a project euler problem.

comment Reason why these two probabilities are equal (Picking Balls in exact order without Replacement)
Intuitively there is a degeneracy between "sublevels" of the same ordering (i.e there are 12 different ways to pick AAABB but they are equivalent). Thus there is nothing special about one ordering versus another, therefore you would expect results that only differ in ordering to have the same probability.

comment Throwing All Numbers From 2 to 12 With Two Dice
What do you mean by "expected". In other words, at what probability threshold do you draw the line - the probability of all numbers appearing approaches, but never hits 1.

comment How can there be multiple irreducible representations of a group each having distinct dimension?
@Jack since the markup is a subset of latex, the command syntax- $\color{color-you-want}{text}$ will introduce color in the math expression (i.e. within dollar signs), if you want colored text - place the text within a math-mode \text{text-goes-here} command

comment Divisibility of 9 and $(n-1)^3 + n^3 + (n+1)^3$
@Theo funny that I had seen weierstrass p-functions without the script p. Is the W-p relevant in this situation (with the polynomial presented by Isaac) or is it just a stylistic variation on his part?
