Yeah, I see what you mean.

Personally I think the XJ200 looks like the proverbial horse's bottom. Each to his own

Which part of the country do you teach, out of interest?

a) It's British. Very important. b) It looks great. c) Damned fast. Plus we're not in the Euro (thank god), still good old Sterling Pounds.

ExtraSense: take a hint, and stop posting this pile of abundant piddle.

Have also renamed the "Competition" forum to "Math Problems" since that's generally what it's used for nowadays. If you have any new problems etc, then use that forum.

You can get an (admittedly older) XKR second hand for under £20k. Probably won't be the supercharged version, but it's an absolutely awesome car. Still got my eyes set on the V12 5.7l E-type soft top though

I don't think we can drag this out any more, so I'm closing the thread. Comments/pleas/hate mail to my pm inbox or e-mail if you're so inclined.

Yeah, unfortunately it's pretty much illegal

If it makes anyone feel better, this problem (the Monty Hall problem) was debated over and over again (and still is) for about 10 years before it was generally accepted.

Hmm. I'm just wondering whether an alternative formula for an exists.

Sounds like a pretty inefficient method of prime-finding to me; that certainly won't win you any awards.

Well he blatently won't, because then he'd lose all credibility. As long as he can ignore the questions that will disprove him and modify others to suit his needs, then he'll keep selling books.

Got a proof? And good luck trying to find the infinite series, looks like a pig, specially with that damned [x] crap lying about.

Jaguar XKR will knock the pants off of that viper. Mighty fine British engineering for you

Agreed. (hi btw)

Since you have f(x) defined to be the function 3x2 + x2 - 12X -4, can we assume x = X?

I think that this topic has been completely exhausted. It's all a matter of definition, which personally I find rather dull. But anyway, does anyone have anything fresh to add to the topic? Otherwise, I'd rather just close it.

My advice is to go and take a physics course

LaTeX renders fine. [math]n = \sum_{n=2}^{\infty} gn[/math] etc. You almost certainly need to define that function in a much more rigorous mathematical fashion before it's taken seriously. I don't really understand what you're getting at atm.

He didn't forget anything. Basic order of addition/subtraction/etc that I learnt when I was back in primary school.

Mathematica, Matlab, Maple are three commercial programs that are available for purchase over the net. They're pricey though; I recommend Mathematica though.

I think that was the condition, although I could be (and probably am) wrong.

Unless you can conclusively prove that your formula works for all prime numbers, it's not a proof.

I suspect he may have posted post #29.
