Maths...

Since i've been 'stuck' in my bed for a while for the past few day, i've been going through my math olympiad file. I saw some cool problems. The main topics i was looking at were number theory and pigeonhole principle. Quite powerful concepts. Haven't tried any problems yet. I'm still stuck at the differential equation.( dy/dx= x^2 + y^2 , find y in terms of x). I was told that it was not doable, so i guess i'ld have to pick up some new problem to work on. But i really learnt a lot while working on this differential equation (eg. i learnt how to solve exact, 1st order differential equations) . My friend asked me to try and seperate the variable. Well, i haven't tried it yet. When it comes to differential equations, I know how to combine variables, but not how to seperate them. It's just the reverse process that should involve introducing a parameter, reverse of the elimination of parameter when combining variables. I guess i'll spend a bit of time on it now...

Oh ya... I saw the nyjc's new mass dance on youtube. can click here to get there. Think it's a kinda remix.

AND there was also this leaked acjc mass dance video posted. It came up when i finished viewing the previous video. There's some argument going on on the page that may be worth checking out too...haha That's all for now. stay tuned! (back to my ODE)

p.s the O is striked, but it look like theta.


Well, it's time, so here's the video i was talking about. When it first played on the radio it sounded like quite a bad song. But upon further listening, it was very good, like their other songs:
