there's a version of that (in colour) on my dad's nokia, can't remember which phone he's got though offhand.

I'm also moving this over to stats as it has nothing to do with calculus as such.

I can't say I've taken any cryptology courses, but if you're interested in the maths behind it, then learning about it isn't too hard. Some main concepts behind the latest cryptology techniques mainly revolves around modular mathematics. It all depends on what you know already.

I'm not really familiar with this concept at all. Got any links to any other pages that introduce it at all?

Hmm, I'm not entirely sure you know what you're on about there tbh.

I've never even heard of it until today to be fair. Apparently it's an extremely rare occurence.

Hmm, not quite sure why this is in general computing, but it's a bit annoying that people decide to monitor yet another thing in our lives.

I have to admit, that sucks a lot. You can't even swim in a bloody lake for fear of being killed by a microscopic piece of stuff.

You said it, not us

Yup

They showed outbreak on ITV at 10pm on a wednesday night, which just summed it all up for me

If it doesn't have a list of cheesy chatup lines, I'm not reading it. e.g. "Get your coat love, you've pulled!!!!!!", "Here's 20p, phone your momma cos you ain't goin home tonight!!!!!!!!!" etc.

You spell mathematician like that. I'm going off to study maths this year, and I'm now 18.

space invaders is overrated, never liked that game

Having thought about it, the core this year takes up 75% (which is quite a lot) so I have that to play around with from the other options. I think I'll probably end up taking something like 4 maths modules and about 4 physics modules, which'll mean I have another 2 modules to get extra credit from.

I'm doing maths at warwick university.

It's what double integration's all about. It's not terribly exciting to be honest

? There ain't nothin hard about it, it's just seeing a method.

I tend to do that anyway most of the time

Okay, I can't be bothered waiting for someone to reply, so here's the answer. Let x = sqrt(2 + sqrt(3)) - sqrt(2- sqrt(3)) This means x^2 = 4 - 2*sqrt((2+sqrt(3))(2-sqrt(3)) = 4 - 2 * sqrt(1) = 2 Therefore x = sqrt(2) There we go. Ta da etc.

Differential equations are mainly easy at a basic level. Vectors are a pain in my opinion. Partial derivation/multiple (i presume double, maybe triple) integration is pretty cool, allows you to find tangents to planes, volumes under planes and the like.

okay, after thinking about this I realised that I was being completely stupid. The question itself is completely trivial when you just look at it. The key word here is 'derive' - hence you have to prove it yourself. here's a pdf with the answers in (too much time on my hands ). scistuff.pdf

dudde's been in there quite a bit recently

as for the original question, i'm not really able to understand it tbh - if x = 0 initially you have a problem no matter what value of c you use. is this actually meant to be a find the integral question or draw lots of graphs out, or what?

miles davis is simply amazing, coltrane's good too. i'm into both the big band and also the more modern jazz (but not the kind of stuff they usually play on things like jazz fm)
