  1. That's really quite cool (with the drag thing). Be great as a toy when they get the satellite imaging
  2. If you're looking for an implementation of Visual C++, you might want to try: http://lab.msdn.microsoft.com/express/visualc/default.aspx They're doing Visual Studio 2005 "Express Edition" versions of the software for free - which is always a good thing. I do like the IDE.
  3. Muahaha. ph33r the sk1llz
  4. I'm a little confused as to the method you're using - or just generally what the problem is. Care to elaborate further?
  5. Win2k likes to be the on the primary drive. Basically, the idea is to map the hard drives over so that win2k thinks it's on the primary drive. Off the top of my head, if you had linux on hd0 and win2k on hd1, then: map (hd0) (hd1) map (hd1) (hd0) chainloader +1 Might do the trick. It's in the grub documenation. I found WinXP to be an even bigger pain in the ass (had to chainload individual partitions to get it working).

    It's not that rare really. Mainly I think they're due to manufacturing defects when you buy the monitor. Happened to me, but it's hardly noticable at all. If they're right in the middle, then it gets rather annoying, but otherwise you should be okay.
  7. You mean something like: [math]\widehat{AB}[/math]?
  8. Well, the owned license is about that much. For a leased license you can expect to pay around $80.
  9. Oh well, this just shows how I got 47% on Probability A
  10. In that case, dan's answer is the one you're looking for.
  11. If you want multi-line stuff for things like systems of equations, you can use the equation environment along with the array environment.
  12. I read this: Then I laughed. Then I closed the window.
  13. This is a pretty common problem - I've had it a fair few times. Which bootloader are you using? You'll probably need to chainload your drives. I'd suggest grub for your bootloader, as it's far to superior to pretty much anything else.
  14. That's what I got a couple of days ago. I was just scared to post because I haven't done probability in aaaages PS: You can use \cap for the intersect symbol - [math]\cap[/math]

    USAMO studying

    Personally, I hate these kind of things (I did the British equivalent and failed miserably ) but the best way of training for these things is to tackle lots of past questions. They're written in a certain style - you can train yourself to a certain extent. I never saw the appeal personally.
  16. I was talking to my dad the other day, and he was saying how he'd watched a documentary on this a while back (don't know the name, sorry). One of the more interesting methods of doing this is actually to learn how to properly use an abacus to work out the multiplications, divisions and additions. The documentary was all about a class of kids that trained their mind on using the abacus for a couple of hours a day - I think it was in one of the Eastern countries. After a couple of years of doing this, they were able to abandon the abacus completely and just picture it in their minds. These kids are able to multiply two 5 figure digits in their head and give you the answer within a couple of seconds. Now, I'm not saying that you should do this - it's probably never going to be necessary for you to multiply large numbers in your head - but it does give an interesting insight into how powerful the human brain is if applied correctly.
  17. I think I'd agree with Spyman's interpretation of the question, but dan's method for his particular interpretation appears to be correct. You're also assuming the balls aren't being put back in the bag
  18. I would start by explaining the trivial case of y = x - i.e. 1 unit along is equivalent to 1 unit up. Then I'd explain the notion of the gradient, and how this affects the value of m. I'd conclude by adding in the constant to show how it shifts the line up and down.
  19. For me at least, it's two things: 1) Being able to prove things using the knowledge I've already aquired. There's nothing quite like proving things in maths - although it sounds sad, it's quite fun. 2) Passing on my knowledge and experience to others and helping them to understand the things that I had trouble understanding.
  20. Just a warning for you people: if you use the wysiwyg editor to edit posts that you've made using [math] tags, then you'll run into problems when you hit the submit button because of the way the wysiwyg editor interprets images. In short: don't use the wysiwyg editor for LaTeX unless you need it badly. It breaks things
  21. There's a thread in the General Mathematics section, stickied at the top.
  22. Euhm... I believe 0,6 is equivalent to 0.6 - in some European counties, a comma is used instead of a dot to indicate a decimal number.
  23. There's loads of threads already on this. Have a look around before posting a new thread on it
  24. You can form a pair of simultaneous equations: [math]x^2 + 9^2 = r^2[/math] where r is the radius of the circle, and: [math]x = r-3[/math] Substitute the second into the first and you're done.
