To solve an inequality like that, one way is to graph

So the turning point is at

However, due to the modulus sign, we must reflect every negative y-value about the x-axis, so the turning point of

So when you sketch the graph it should look like a normal parabola except the part between the x-intercepts has been reflected about the x-axis. This graph should cross the line y=2 at 4 points, and if you graph you will see there are two sections below the line y = 2.

To find the intercept between the two graphs,

So for

I think Identity is wrong. Try

I don't know how an ark fits in with the lever ?

Stephen Hawking was born on the same day as Galileo Galilei, exactly 300 years later!

I also remember there was another cool birthday/deathday coincidence but not sure which was it was, maybe it was:
Einstein died 100 years after Gauss.
But I think it involved Ramanujan... alas I have not been able to find it.

Oh yeah and I forgot to say, I saw star trek and it wasn't what I expected but it was still awesome! I have to get the DVD!

hope these are right xP

Oh stop making me jealous

lol I really want to see it after I get my exams done with

What is Reciprocal Multiplication? Can you give an example?

Harry Potter, whenever it comes out

Thanks Kurre, I'll try to find it in the list. However, it is not Ceva's theorem or Menelaus's theorem.

I remember seeing a wikipedia page on it - it was a very advanced proof I think, but still uses Euclidean geometry somehow

Are they primes?

Since this must be a cube,

No solution?
