And the rest of the 'proof' is thus:
Let the number be n
We know that two of the 4 smallest divisors will be 1 and 2.
If another is 3, then we have n = 1 + 4 + 9 + a^2 = 14 + a^2. a/n, so a/14 (as a/a^2). We check 7 and 14, and they don't work.
Therefore 3 does not divide n
We check...
Yeah, I know now. I thought he was because he mentioned meeting chris at the talented students day and I saw Jordan there, and I didn't think many people from Wollongong would be there.
If you were rigorously proving this, you'd have to first prove that f(a) = f(b) ==> a = b, but that isn't too hard.
f(a) = f(b)
Therefore f(f(a)) = f(f(b))
Therefore 6a - 2005 = 6b - 2005
Therefore a = b
What do you get when you cross an elephant and a monkey?
A vector with magnitude Elephant Monkey sin theta and perpendicular to both of them
What do you get when you cross an elephant and a mountain climber?
Don't be silly, you can't cross a vector and a scalar
Also, see my sig.
