11, Module 3 retake.

Awesome. Haven't met any other Y11's except SM, PA and IRW. Did you do the GCSE already?

SteveM4 · « **Reply #102 on:** November 15, 2010, 01:50:03 PM »

Yeah, did it in June. Got a high C

The four of us covered all of the GCSE stuff in Y10, but we won't do it until June.

Explain why (n^2 - a^2)-(n-a)^2 (when n and a are integers) always results in the result being even.

Any integer (Z) multiplied by itself, positive OR negative will get a positive integer, so as long as both n and a are integers, n^2, a^2 and (n-a)^2 are even integers (multiples of 2).

Any simple operation with only even numbers (adding, substracting, multiplying, NOT dividing though) will yield an even number as result, so n^2 - a^2 - (n-a)^2, being an even number minus 2 even numbers, is an even integer.

Not really "right" as such but it'l do I guess.
You needed to prove that id the first bracket was even, then so was the second (Even-even=even)
And when the first is odd, the second is odd, (Odd-odd=even)

In your reasoning, a^2 and (n-a)^2 have to be even, but odd numbers squared = odd numbers

BUMP!

Seeing as
A) you guys completely lost me here
B) nary (at least i think it's nary) hasn't asked his question for the best part of a month

NEW QUESTION!
In square meters, What is the volume of a single chunk in Minecraft? (assuming each block is 1m x 1m x 1m)

Squirrel_Monkey · « **Reply #107 on:** December 03, 2010, 10:34:02 AM »

It isn't, volume is in m^3 not m^2
But it's 1m^3

J24 · « **Reply #108 on:** December 03, 2010, 10:44:49 AM »

I Meant in m^3
anyway, nope, thats the volume of one block

Squirrel_Monkey · « **Reply #109 on:** December 03, 2010, 10:47:54 AM »

32,768m^3

Yeah

Hydro · « **Reply #115 on:** December 03, 2010, 11:20:25 AM »

Scientifically, I am correct.

Squirrel_Monkey · « **Reply #116 on:** December 03, 2010, 11:25:32 AM »

Just no, white doesn't count as a colour. And no flag's white is perfect.

White's just an amalgamation of red, green and blue. If you look at it from a Physics point of view. The Republic of Karelia has all three, yet no white.

Hydro · « **Reply #118 on:** December 03, 2010, 11:29:58 AM »

So is every other color...

Oh well. NEXT QUESTION :D
