Going flat out, I write an HSC booklet in 50 minutes. But thats only like 1200 words, legible but not pretty. And my hand hurts like hell afterwards. I think I'll have to try the weight on the end of the pen idea.

yes.

tan(pi/2) can only be dealt with when you use tan^-1(tan(pi/2)) I was trying to use the first U(0) we get and minus the second U(0) we get. ie \frac{1}{2}\int_{0}^{\pi} \frac{2}{5-4cosx} dx = \frac{1}{5}\int_{\pi}^{0}\frac{4cosx}{5-4cosx} and then mess around with that.(I dont like latex) :)

I think the same answers were just a complete coincidence. Using the t method we get the answer as pi. There is no reason not to believe this. I get the same answer with the other method, I don't know what it is. There doesnt seem to be any problem with the proof or with the method, so we...

Definitely not I would say... I think it is mathematical nonsense and btw if we do the working with tan properly, we get the answer as Pi

This seemed quite strange to me, however, my calculator agrees that you can do this kind of thing. However, it gives me an answer of 3pi/2. Seems reasonable enough.

Just wondering, in studyfreaks solution, what happened to the 2/5 in the third line of the second part?

"fair proportion" < 50% "sexually active teenagers" - kind of a target market for this survey "or know of friends who have" = its not very common. Good work The Age, you pathetic excuse for media.

As much as I think you're homosexual dog topic was brilliant, I would like to say that coffee is pretty terrible. People make it not taste like coffee so they get the caffeine hit, possibly they also have homosexual tendencies in which case we could go let those dogs onto them. I drink coffee to...

i hate ethnic girls. and ethnic guys. and females in general, especially those who want equal rights. and ugly people. however, i love fat people; their bad health means I get to lie on them more comfortably.

Pretty sure the main reason people here are single is cause they're the type of people so cool as to spend time at boredofstudies forums discussing relationships. However, I'm reppin' the single kids. It's the best way to be.

only almost completely wrong. the body sleeps in 90 minutes, but it is the last 30 minutes of this cycle that is the beneficial sleep. you can train your body to immediately enter the beneficial phase of sleep, but that's quite the bit of effort and only worth it if you keep with a polyphase...

I have never been fit, or any semblance of strong. I have, however, always been able to get a solid 10 in the beep test and do 20 real push ups. Make sure the beep test you're doing is actually 20 metres. even 22 metres makes a huge difference in what you can reach. You don't even need to...

"Physics is the only real science. The rest are just stamp collecting."

you've done chem already. how'd you go? then theres 2 units of english have to count. u seem to like eco, so thats another 2 units you'll use. sure, sor is boring, but easy. 1 unit or 2?

Re: 回复: Re: integration \sin^{-1}x = u x = \sin u \frac{dx}{dy} = \cos u dx = \cos u . du \int \frac{u \cos u . du}{\sqrt{1 - sin^{2}u}} = \int \frac{u \cos u . du}{\cos u} = \int u.du = \frac{u^{2}}{2} at least thats how i got it. do I then have to put it in terms of x?

We need 3 hours of sleep a day. But thats the good, deep, kind of sleep. In order to achieve that we need 9 hours of sleep in a row. However, when i say need, i really mean should have. You can sleep for 7.5 hours and be fine, with no repercussions. When you cut that to 6 generally you will...

refer to the constitution, section 116. stfu protesters.

English is gay. Everyone spends too much time on it. Or they fail. The English subject needs to be reviewed.

It goes alright but the 4 clubbers version is better. Still not an amazing electro song. Best dance song ever: 'Come With Me' by Special D Just as an aside; electro, techno etc all get better with more volume.
