Just to think PF has 5 hours study done now and I'm not starting until 12 is sickening :PDwellingdweller wrote: »Awh, I was there too! I went to the mathsci booth as well, were you chatting to the guy who had the really bright eyes and who was kinda camp? Not mathsy looking at all, kinda? :P The environmental science guy was cool too, and the girl at biopharmaceutical stand was lovely
I was standing chatting to the blonde one at the Economics stand too for like an hour haha, she was so sound! What did you reckon of it overall? 
Haha yeah pretty sure that's the one I think he had a small lisp aswell! It was kinda awkward because everytime he said something I would at the same time and we'd both just stop. I had a nice chat to the weird old applied maths guy and he was hilarious :pac: But yeah I thought it was good enough! I'm definitely going to NUIG anyway it's just such a nice college, not too big or small and right beside the town 0 -

Haha that sounds class! He was such a sound lad Cool! Did you meet the two PhD mathematicians? One of them was half brazilian (and working for Aerobus), he was in the lab, I was talking to him for like half an hour :P And the other guy had black curly hair and glasses, he gave a talk on the 'student experience in science' if you remember him? He was hilarious :P He also gave me a half hour introduction to M-theory afterwards too, he was so sound like!I know people have LC nightmares, but has anyone had a future career nightmare? I did last night and it was so weird
What was it? I'm always worrying if I'll like my career. :P0 -

I was talking to a lad at the stands in bailey allen hall, I was at the labs last year anyway so I think I know those guys:P Sure when I go to NUIG library I often find myself reading the maths college books! They're actually ridiculously complicated! Especially the astronomy type books :eek: It's like a different language there's no numbers in the book like :P0 -

Strange thing happened today, I was completely stumped in my maths mock paper 2 q8. Couldn't put anything down. It was the one with the eco-tunnel thing if anyone remembers.

This the one? In my actual pre I completely blanked for that one, guessed the radius, lost 20 marks and with them my A1.

It took me an hour of staring at that blankly to figure it out. Luckily I had the other pre!0 -
Our probability was only a tiny bit with no thinking involved so I cant excuse my full marks there, but I got 0/25 on the line because I didnt realize the co-ordinates could be in terms of the variables...get on my level :PYeaaahFaoiSin wrote: »Got 5/75 on the Probability/Line part of my Mock. Get on my level
I didnt even think to do that, and would never have thought of the actual way to get the radius. :pac:I thought that was where I was headed and I was freaking out, so I cut my losses, guessed the radius and used that in the other parts of the question. The annoying thing is I actually thought of how to do it in the exam, then decided "no, that'll never work". :L
The 6 marks I got were really down to the over-generous marking scheme and me using my protractor, writing down the real value of the angle and writing 's = r theta'. I am special :cool:0 -

Seeing as we're on the subject of maths, if any of yis could help me out with this question I would really appreciate it! I know I'm missing something simple but I can't for the life of me think what :pac:
p(2,-1) q(3,5) r(1,k) are the vertices of a triangle of area 7 sq. units. Find the values of k.
I've tried every formula for getting area and let it equal to 7 but I dunno... I know when it says values I should end with a quadratic but I just can't get it! Thanks in advance guys 0 -

Reduce the first coordinate P to zero and transform the remaining coordinates with the same values you used to reduce the first to (0,0), apply the coordinate geometry area formula and equate it to 7.0 -

That's what I would've done as well. Most people I know seem to completely forget about that formula though. Was it not on for the Junior Cert? 0 -
