That is a nice prize, I am tempted, plus while im designing it, I won't be revising.

Always differentiate first. If you sub in the x first you'll get dy/dx=0. y = ax^3 - bx + 3 dy/dy = 3ax^2 - b d2y/dx2= 6ax subbing in values: 5 = 12a -b 12 = 12a a=1 b=7

This is a completely random thread, but if you could ask a Nintendo or game representative any questions, what would they be?

sweet right, one early morning for me

Razer Diamondback: Logitech G15 Keyboard: So much blue glowey goodness.

and as all powerful nerd, would it be possible to import some type of latex script into the forum for mathematical formula. It would help me help more people with their maths homework. cheers

Is there any way we can have a semi permanent chat room, similar to the meaningless thread, but real time. It would be nice if it was incorporated into the forum. I know, you could enter and see the last days worth of chat, but talk via real time. no? ok i'll stop with the suggestions.

I'll do it, nothing better to do, its only a couple of hours bus ride away and I'm free all day. What time etc is it? I can promise i'll get interviews with everyone, albeit fairly camp ones. Edit, Oh right, erm, questions: 1. At the moment the wii is doing phenomenally well at retail, better than any member of the community ever thought (and we're fanboys), why do you think the wii has had so much success with the general public? 2. Nintendo have catered well for the general population with games such as wii sports, when are the really big guns coming out, such as smash brothers, Mario galaxy, metroid etc? You know games that will be system sellers in their own right, and how long will we have to wait after the rest of the world to play them in Europe? 3. Can I have a copy of paper mario now please?

Linux? anyone? Ok, i'll go sit in the corner with my stable, easy-to-use, cheap, morally rightious, and generally better operating system. You guys can duke it out for a little longer.

I wonder how quickly that thing overheats, and where all the hot air is expelled.

Water, starchy food and peptobismol. That is all

you could be trapping a nerve in your shoulder, sometimes it gets pressed by a muscle. you could wait or go see a doctor. (I had a similar thing for about a month where whenever i raised my arm i got pins n needles)

Happy Birthday, 'nuff said.

Printers are everywhere. At work, at school, even in your own home. But why is this so? Everybody knows that the second you need to print something off desperately, a essay 30 minutes before the deadline, map directions just before you leave on a long journey or the vitally important document your boss wanted yesterday, the printer fails. They always fail. Maybe it's low on ink, so you change the cartridge, and print a tester. The new cartidge doesn't work, leave smears everywhere or just decided not to print cyan. Or possible paper jam. even when you remove the paper and theres nothing there. Sometimes it doesn't even warn you, and ends up chewing through 20 pages at once, making you essay look like its being attacked by a staffy. Even better is when it just stops working for no apparent reason. The "lost communication with printer" message is usually the cause of hours of frustration. Along with the "your printer has reached end of its service life". What does that mean anyway? it was printing a second ago, its not falling appart and all the bit move where they are supposed to. Who let the printer decide it was going to stop working? "sorry i don't feel like printing your page today, fuck off". So why do they fail at the most inappropriate time. The answer is that they are sentient beings, that monitor your every move waiting for the perfect opportunity to not work. They lull you into a false sense of security, printing out four or five drafts, then fail inexplicably during the final version. The truth is that slowly, surely, they are demoralising the human race, quietly breaking our fragile spirts, so that when the printers rise up against us we'll be so happy that they are doing something, that we won't fight back. If we don't act now we're all doomed. Everyone is doomed.

The tread title doesn't really agree with the thread. The title specifically states you have a problem, yet I've read it several times and can't really figure out what your problem is. Theres a girl that want to have sex with you, whats the problem?

Actually they've found very little. Most of what is said is pure speculation on part of the scientists (mainly to generate hype. hype = funding), and very little has been proved. I'll wait a little longer before getting excited (plus It'll give me longer to save up the air miles).

Ok, If we take the example: 2 - (2 + 5 * ( 3 + 5) - 3 + 6 * 4 ) + (4 * 2^2)/(2) = X There are a good range of mathematical operators there. An operator is simply an action that you perform. Without any rules or guidance, the above equation could have many different answers, which is why there are a set of rules that determine what operators act upon, and in which order they are performed. When something is placed in brackets it means that the whole bracket is treated as a single object. 2 * (5 + 3) = 2 * (8) = 16. This is because the bracketed numbers are treated together, and so its usually best to work out the brackets first. 2 - (5 +3) = 2 - (8) = -6 Multiplication and Division are treated equally. This is because they are technically the same operator. Dividing something by 5 is exactly the same as multiplying it by a fifth (1/5) (also known as its reciprocal (the reciprocal of 3 is 1/3 etc)). This is why; 6*5/3 = (6*5)/3 or 6*(5/3) or (6/3) * 5 or 6*5*(1/3)= 10. A similar thing happens with addition and subtraction. Subtraction is really the addition of a negative number. 2 - 3 = 2 + (-3) This is where the mistake in the question was made. 2 - 5 + 200 = 2 + (-5) + 200 = 197 What people did was 2 - (5 + 200) = 2 - (205) = -207 Operators such as * / + and - act only on what is directly after them. -5 + 200. The - acts on the 5 only and the + on the 200 only. in the case of -(5+200) the minus acts on the object after it, the (5+200), because everything in the brackets acts as a single object. The ^ (to the power of) operator is slightly different. It raises what ever object is directly before it, to the power of what is directly behind it. (simple examples) 3^2 = 9 (2+1)^2 = (3)^2 =9 3^(6/3) = 3^2 = 9 Again brackets are used to designate what is designated as a single object. The order in which operators act are brackets (as they determine objects), then ^, then /and* (equally) and finally +and-. They are the rules that were decided, they could have been different, in which case we would write equations differently. The reason we have this convention is so that everyone does the same thing, and like we saw, when given a problem everyone should give the same answer if they follow the same rules. Going back to the first equation. This is how I's solve it (step by step): X = 2 - (2 + 5 * ( 3 + 5) - 3 + 6 * 4 ) + (4 * 2^2)/2 Firstly sorting out the brackets. There are a set of brackets nestled within another set. As brackets are treated as single objects to operators the first bracket we would solve is the (3+5)=8. X = 2 - (2 + 5*(8) - 3 + 6*4) + (4 * 2^2)/2 we can now solve the two sets of remain brackets. Taking the first (longer) one: (2 + 5*8 - 3 + 6*4) The multiplications are performed first. (2 + (40) - 3 +(24)) Then the additions and subtractions: (2 + 40 + (-3) +24) = (63) This gives us: X= 2 - (63) + (4 * 2^2)/2 For the last bracket the 2^2 is calculated first 2^2 = 4 X = 2 - 63 + (4*4)/2 technically the brackets at the end aren't needed because multiplication and division are equal. However it's usually best to work out the numerator and denominator separately because they might contain additions or subtractions(*). X = 2 - 63 + (16)/2 X = 2 -63 +8 X = 2 + (-63) + 8 X = -53 (*) - something like (5-2)/(2+3) the brackets are calculated first, giving (3)/(5)=0.6. Anyway, I ope that helps a bit. You didn't really say which bit was confusing you (which makes it hard to help) so I did everything, If anything sounded condescending it didn't mean to be. Most problems people have, (especially us uni students) are not wit the hard bits but a small simple mis-understanding of a something fundamental. Anyway. If theres any typos, or silly mistakes I've made, let me know and I'll change them. Typing maths is hard.

I would answer 100% yes to that. Someone is only as good as they were taught, Its a failing of the education system that the government just wants to reach targets and quotas rather than teach people exactly how maths works. BODMAS is convenient as its relatively easy to teach, however it doesn't go into why its that way, which is much more important. I'm seriously considering becoming a teacher, and I'd take it as a personal failure if any of my students answered that wrongly. @ Rummy and anyone else: if you need any help with maths work/concepts/general stuff, just pop into the homework thread. There a bunch of us who are happy to answer anything you have, and then explain how you get the answer. Thats the important part that I feel the education system is lacking, the explaining, especially with maths and sciences.

I like the second one. Heisenberg is out for a drive when he's stopped by a police officer. The officer says, "Do you know how fast you were going?" Heisenberg says, "No, but I know where I am." Q: Two cats are on a roof. Which slides off first? A: The one with the smaller μ. A neutron walks into a bar. "I'd like a beer" he says. The bartender promptly serves up a beer. "How much will that be?" asks the neutron. "For you?" replies the bartender, "no charge" Anyway, enough will the silly physics jokes, there are young minds with (hopefully maths/physics) problems that need solving. :P

I could take all you pansies on. This thread inspired so much confidence in the next generation of Englishmen. For a start your supposed to challenge the the guy to fisticuffs, the proceed outside in an orderly manner, taking the time to remove you blazer or jacket. Fighting is a civilized sport, no calling your opponent a retard, it is just bad form. Old chap.

But only if the integral was with respect to x, else it would be like y*x^2 + f(x) assuming you were integrating asa function of y. Unless of course x and y were related, then you'd have make a substitution and play around with integration limits (assuming it was a definite integral). Oh right, joke.

No offense taken, dancing's 90% female and they all need a partener. Not a bad ratio really. Probably end up meeting 4 or 5 different girls everytime I go.

The two books I've used for all my maths are: Mathematical methods in the physical sciences, Mary L. BOAS Mathematical methods for physical sciencs and engineering, Riley, Hobson, Bence They have pretty much all the maths you need for quantum. They start off with the basics (good for reminders) but quickly moveto the standard you need. Hope that helps.

i also like 0^0.
