Hope that is kind of clear...

Also meta, I know what you mean about not feeling the competitiveness so strange, I guess it's because we all want it and we know that others do just as much :smile:. At least I'll be seeing ya there, maybe we'll get aggressive lol.


Yay! that's what my diagram looked like! (experiences a pathetic amount of happiness from one answer..!)
As a point of comfort on the maths btw, that is the hardest question i've ever seen by far (i've looked at a few sites which have write-ups of peoples interviews), and often they are of the level 'draw y=5x/2'. also, i imagine that they only ask the most difficult ques to people with FM who will have definately done the unit which the knowledge is needed from.

Seems like a big jump from that question to y=5x/2.

Hmmm i know. I know which one i'd prefer! then again...maybe they only ask you the ones like the mod one if they think you're clever...

On that point of subject based interviews, I have never done economics and although I expressed interest in it in my PS and stated I chose it instead of physics (my passion, I chose econ because it is ridiculously interesting and important, physics can be done in my own time). Back on track, I didn't actually show too much knowledge in my PS just what I have followed in the news and a book I have half read. How in depth could my Econ questions be? Will they just test my analysis and my ability to adapt with what I learn etc. or could they give me a real 'problem' to solve like people who have done econ A-level. << I'm panicing because who knows if I'll get lucky with an econ problem or not...

Please post the website :biggrin:

there was another one too but i can't find it. If you click on the profiles and scroll down there's usually a short write up of stuff that was asked. I'll let you know if i find the other one.

I found out by asking my maths teacher what it is! The other guy was right, it's a square going through all the coordinates of 1 (including -1). If anyone wants an explanation pm me and I'll explain. It's really simple just needs explanation! I'm on my iPhone which is why I don't want to write it all out.
I'm talking about rosa.s's |y|+|x|=1 graph.
Right, so I tried it again after you said that and looking at my modulus notes and got:
|y| + |x| = 1
so y+x= -1
and y + x = 1
so
y= 1 - x and y = -(1 + x)
so when x and y are 0 you get: y = 1 and -1, x= 1 and -1
doing the graph of y = -(1+x) gives the bottom bit of the square I think but I cant get to the other bit,
explain?

God I am not looking forward to the economics interview; its my favourite of the three subjects but there is no room to blag when it comes to the technical stuff. If I get in a tricky spot in the others I can always digress or bring up an interesting quote from a book I read, but am helpless if faced with a question like that.


Haha.. Im the complete opposite. Im so utterly unprepared with reading and stuff that Id screw up even blagging. Technical stuff Ive actually done in school would be awesome :smile:

It seems jacobwilliamson knows, he said its a diamond!! How odd... Seems an educated guess doesn't work then maybe with explanation I'd get it... I though mod means any value you put in the | | is positive? Leading to my interpretation with |y| all positive and -|x| all negative then shifted up one... Jacobwilliamson can you help please and explain? I know this isn't a maths forum but one more post can't hurt. I am so :confused:


|x| can be treated as x unless x is negative, in which case it becomes positive. the same applies, obviously, to |y|.

therefore... just plot a few points and think about it:

|x| + |y| = 1

if x=1, y must equal 0
and at the same time if x= -1, then |x|=1, making y 0 again.
so you can plot the points (1,0) and (-1,0)

and the same applies if y=1, or y=-1, then x=0.
so you can plot the points (0,1) and (0,-1)

see the diamond appearing?

Yh, jacob I think my problem was that I considered the equation before the graph. When considering the possible coordinates first and putting them into the equation |y|+|x|=1 it's easy. My teacher just said think of y+x=1 in quadrant one, so I did and drew it. I got a straight line from (0,1) to (1,0), so that for any value of y, the respective x value gave a total of 1. Then he said now think of what mod brackets do to numbers and your there, so I realised that this line would ignore the negatives and could be plotted as a square through (0,1), (1,0), (0,-1) and (-1,0). When I say square I mean square on its side (diamond - I just always think of diamonds like a rhombus). If you draw it you can then put any coordinate values into the equation and because of the mod brackets you will always get 1.

I hope that is bordering on a clear and final explanation :smile:, just look at the bad graph and the intersects given above and you'll have it, I felt quite strange when my teacher showed it to me because it's so obvious but it just isn't for most of us! I guess because of the whole not considering possible points first thing, our automatic reaction is to rearange it first then plot and work through the transformations etc. Hope this helps :smile:.

I start my prep tommorow, I'm reading the economist, newsweek, the FT, wall street journal, the times and the guardian. Then various things online and I'll read my latest two issues of new scientist because of the fact that my teacher said the philosophy tutor may choose to focus on my studied A level, like ethics within biology and physics. Also the role of religion etc in history, so I'm going through some old notes for a broad overview of what I've done. Then I'll just consider the whole mixing pot and try analyse it all. I'll read my book mentioned in my PS on the train and I'll go through some things to do with politics and philosophy on saturday and some of the stuff mentioned by London Prophet :smile: Hard work is due ah well my teachers gave me extensions for my coursework and said 'take the day off' tommorrow so some pressure is off!! Prep is difficult right? btw I'm reading so much because I kind of want to, I don't think it will be that big a help anyway!

I was looking through the thread for the meet on the 10th for something about PPEists that I thought I saw, but I couldn't find it. Can we organise a meet at the same place they are on either the 8th or 9th? I think it may have been in this thread I saw it too but I'm not sure. So anyway going to G&D opposite christ church as a group would be good, meet and chat with ice cream (on a cold day :smile:). This sound good? If it does, I could maybe PM everyone in my list or someone else could... Anyway if you guys decide you like the sound of it and I doubt many of us will be there for wed night then just say and we can set it up!!
Sounds good, didn't we say Tuesday night sometime?
I'm coming! :tongue:

Anyway, for those around on Tuesday night I think that the ice-cream place at 8 sounds good. How many people can we expect?


Lol, I quoted this before and forgot. Here it is for everyone who forgot or didn't know. Tuesday 8pm G&D ice cream parlour opposite Christ Church College :smile:

ok, sorry, ive kinda missed all this previous stuff
i have an a level in maths from last year, but im now only doing decision maths and statisitics (ie not pure stuff)...and i honestly cant remember anything of pure maths. do you reckon they will ask me maths things? shall i look over integration or anything?
sorry guys. just in a panic! x
Mee, if Dewinte goes I'll go, dont want to walk into town by myself I'll get totally lost. I get lost here and I live here :s-smilie:.
Shall we PM mobile numbers or something? Just so that meeting up is a little easier.

I thin k you're right, so by my count we now have Guy (maybe), everestek, Dewinte, Metamorphosis, Me, likewinethroughwater... have I missed anyone?
