I have no idea what I was doing :s-smilie:

ugh, at least I won't make the mistake again.. and yeah, I meant 2 weeks as well, forgot it was half term :tongue:

LOOL, its cool I don't even use my books etc, all my books have been in my locker or borrowed by friends, yeah it doesn't really make a difference as we're on study leave, ready for A2 maths?

I probably would (I like most! :tongue:

) but I've been out all day so haven't seen it.

haha Felix covered me :smile:

he seems to be getting there before everyone :wink:

haha wish I was like you, I'm forever visiting my locker because my teachers are. well they like making sure we have all our stuff for lessons.. started leaving my S1 textbook and chem folder at home towards the end of the courses though :sexface:

and I'm as ready as I'll ever be, not sure what to think yet. what about you?

There don't seem to be many questions being thrown about tonight. Here's one for you all:

Not sure I'm right, so I haven't drawn a conclusion yet!

You know, every year I get a locker, one of my friends gets unlucky so either has no locker or a badly placed locker, so I end up sharing it haha! In the end I hardly use it (half my books just stay in there, no worries about losing them eh?)
My c1 & c2 book have been in there since our courses finished as we didn't use 'em in class lols
Not doing any prep, just gonna get into it, trying to attempt some of the questions on here should be 'brain training' anyways

Is the solution

\frac{\pi r}{2v}

I don't think this is quite true - x is the sum of two square numbers, not necessarily square itself - 2x is then the sum of four square numbers.

Ahh I see, yeah I guess so, i'm planning on doing A2 revision in the Autumn half term :smile:

How were your exams? (I already know the maths results :wink:

) Its so cool knowing international people :h:

I'm intrigued by many things

the unlucky friend :') very nice of you though :smile:

Yup, but you can take it one step further and conclude :smile:

The funny thing is it happened twice last year in my old school, and then in collegel I made a new 'unlucky friend!'
Ahh nah we used to do exercises from it all the time, the questions on this thread! They make you think....a lot! haha

I've only had 2 exams and a practical so far... 7 of my 8 exams are A2, and the only one AS I was just retaking for fun :tongue:

I pretty much finished my AS this January - I finished Maths and Econ AS and finished Physics AS aside from the practical. Only leaving FM AS, which I'll finish now as well as Maths A2 :colone:

So far they've gone alright though. I made one silly mistake in S2 though, I think my streak of no half-arsed bull**** UMS might come to an end! :eek:

LOOL you crazy person! I had no idea you did Econ! :five:

Your murdering these exams, they aint got nothing on you!
Ahh thats good, hmm its cool you may get lucky! Your UMS scores will never be tainted by 1 half-arsed bull**** score, its fine, i'll think of an excuse :wink:

Its good to have the maths together :')

You could. And no, I don't think your n=1 working is correct.

Awesome, I saw 2 ways of solving it but this is entirely different, i'm gonna start your question now, but first I gotta get rid of these hiccups lol and if the fox has a factor of

\pi/2 \approx 1.5

times slower :wink:

The fox has completed half a circle of half the radius when the rabbit has completed a quarter of the full circle!

LOOL, I don't need 'em, makes my bag heavier ^_^ Meh I always act embarrassing, used to it now!
I don't understand half of them, but there's to occasional solvable one (which takes me half a day!), Its not too difficult, I learn't how to use LaTeX like 10 days ago!
just use this website :wink:

after a while you remember the shortcuts http://www.codecogs.com/latex/eqneditor.php

I'm sorry, if I told you that (At least my way of doing it) it makes the entire question trivial. However, you might find that trying it out with some values of x may give you a feel for the question.

(Also, don't spend too much time on it; it's not really appropriate to A Level (Although I can assure you you know all the knowledge required to do it) and I wouldn't want it to get in the way of any important revision etc.)
