Posted January 10, 2009 Surely all this is moving more and more into the modern realms, I thought it was supposed to be folklore and legend type stuff? Things from days of old! Though I can't offer anything on the man-spider thing, I just think of Burnt Face Man. Or maybe the story of Arachne, or whatever that greek thing was. Folklore is still contemporary. Or at least in the sense that folklorists use it. Because the only word they seem to know is folklore so they say it about 10 times every paragraph. But contemporary is fine, the majority of contemporary (particularly fantasy) will be drawing on myths, legends, fables et al. I'm assuming Ashley's already looking at Anansi and stuff? Cause that's pretty HUGE. I know in various versions of myths he's been half and half. Never heard of it but it looks good. Thanks Share this post Link to post Share on other sites
Posted January 11, 2009 Found a few images of what i think your looking for. No stories though =/ Share this post Link to post Share on other sites
Posted January 11, 2009 But not just random deviantarts (although I appreciate the effort) but actual stories, fables etc. These DAs may be based on those, but I need the original, not an artist's interepretation. But thanks anyway Share this post Link to post Share on other sites
Posted January 11, 2009 Maths homework: 1) find the equation of the curve of y=x^2 after it has been translated by vector (-2) (-3) 2) i) solve the equation 2x^2 + 5x - 1 = 0 ii) sketch the curve of y= 2x^2 + 5x - 1 marking significant points. Share this post Link to post Share on other sites
Posted January 11, 2009 1) moving it 2 in the negative x direction gives y=(x+2)² Moving it 3 in the negative y direction gives y=(x+2)²-3 2)i)2x²+5x-1=0 a=1 b=2 c=3 Put that into the equation (-b +/- sqroot(b²-4ac))/2a or you could complete the square, which would give you the coordinates of the stationary point.

Posted January 11, 2009 please do, complete the square lol. for extra marks show your working. Share this post Link to post Share on other sites
Posted January 11, 2009 I hated Maths. I liked the satisfaction of completing a question though, when it all slotted into place. It was pointless in the grand scheme of my life though. --- Anyone want to share their informed opinions of the life and works of Tracey Emin?

Posted January 11, 2009 How about I show you how to do it. ax²+bx+c -> first take the a out of the first two terms a(x²+(b/a)x) +c ->then complete the square inside the brackets a((x+b/2a)² -(b/2a)²) +c ->then multiply out the a a(x+b/2a)² -(ab²)/(4a²) +c -> simplify and then set = to 0 Share this post Link to post Share on other sites
Posted January 11, 2009 I don' know why but I never understand the maths I see online in this thread, seems so much simpler in the book. I can do some of it but thanks for the whole thing Share this post Link to post Share on other sites

I don' know why but I never understand the maths I see online in this thread, seems so much simpler in the book. I can do some of it but thanks for the whole thing I think it's partly that plain text isn't exactly the best format for mathematical exposition, and books tend to simplify and/or present things better. If you avoid quite tricks earlier on (like "move it over to the other side and change the sign"), things will seem more straighfoward as stuff gets more advanced.

Posted January 11, 2009 If you complete the square for that is it: 2x^2 + 5x - 1 = 0 x^2 + 2.5x - 0.5 = 0 (x + 1.25)^2 - 1.5625 - 0.5 = 0 (x + 1.25)^2 - 2.0625 = 0 x + 1.25 = positive/ negative the square root of 2.0625 x = -1.25 plus/minus the square root of 2.0625 I hope it is :/ Hang on don't you have to double it if you divide everything by 2 at the start?

Posted January 11, 2009 You realise that's where the quadratic equation comes from? When I first did completing the square, our teacher told the class to do it on ax^2+bx+c, and you could tell when someone worked it out 'cause they'd go, "hey...wait a second...I recognise that!"

Posted January 11, 2009 Anybody know? I want to know if I failed that or not. Edit: YES!!! I did something right. I am not taking A Level though. That shit is insane. (Don't even talk to me about a Maths degree) Share this post Link to post Share on other sites
Posted January 11, 2009 A-level maths is where it starts to be actually interesting - I don't think many people like maths until things like calculus are introduced, but yeah, the subject is by no means for everyone. Still, lots of people who think they're awful at it could actually be good if they were properly taught. Anyway, GCSE maths is something of an oxymoron.

Posted January 11, 2009 I wouldn't say i like or dislike maths, it's just feels like something i'm doing just for the sake of it. I don't really think A level is harder than AS (from what i've seen), the majority of C3 is just differentiating/integrating and trig functions, though i haven't seen much of C4 yet. Oh i also beat Moogle in C2 by 1 mark (both A's), i'm quite proud of that considering i never beat him in anything else Share this post Link to post Share on other sites

I generally found all my GCSE's pretty easy but maths was the one I really had to work for. I scraped an A, if it'd been harder I would have struggled. But then we did have about 6 different teachers over the 2 years, one of which was an actual pervert who read The Sun in lessons (and this was a private school). Wow tangent, anyway I disagree!

Posted January 11, 2009 C3 and 4 can be tricky, but are usually reasonable enough - I thought the hardest A-level modules were M3, DE and FP3. S gets easier the higher you go, oddly enough... Share this post Link to post Share on other sites
