it is heartening, the number of people who cannot grasp GCSE-level algebra and will pay you good money to explain it to them
altho how many times can i say "do the same to both sides of the equation" before i turn blue, honestly

i have been doing undergrad interviews this week. the kids i've been speaking to are two years older than yours, I guess. they were 'tards, and they are definitely getting worse. easy way to make oxbridge academic laugh very loud: say "let's take GCSE scores into account".

jhoshea can u please solve the following thru factorisation
2x^2 + 2x - 12 = 0
― MATH ADMINISTRATOR, Wednesday, 17 December 2008 18:12 (fifteen years ago) link
jh0, please can you
- differentiate x^(-cos(x))- integrate 1/(x^2 + x - 6)- plot sin(x)/x- tell me how long a day is on the moon
^^^ real interview questions
― caek, Wednesday, 17 December 2008 18:14 (fifteen years ago) link
lol caek, maybe they are just nervous ; )
the GCSE maths syllabus is noticeably easier than when i did it, btw. and props to fighting back against oxford's particularly public-school-haven rep ;)

does not moon day last forever if "day" is "length of own-axis revolution within orbit"

oh riiiiiiiiiiight---we only see one side of the moon basically ever, right? the other side is where madness lurks?

someone post a photo of LJ to help Mr. Que out.
day = "time from sunrise to sunrise" or "time to rotate on its own axis" (give same answer)

this is the crucial fact you need to answer the question
(sub-question is: why do we always see the same side of the moon?)
dudes i cant do maths - gimme a break
― ice cr?m, Wednesday, 17 December 2008 18:25 (fifteen years ago) link
because the moon was created by a super-asteroid impact on earth, hence the clustering debris had no rotational inertia
― country matters, Wednesday, 17 December 2008 18:26 (fifteen years ago) link
because the moon is mocking us always mocking us?

q: does the moon orbit in the same direction as earth's rotation? also, is the orbit normal to the earth's axis, or is it in the same plane as the earth's orbit?
― pretty impressive war skills (gbx), Wednesday, 17 December 2008 18:29 (fifteen years ago) link
jhoshea - the answer is x = 2 or -3
see me after class

ow the moon is freaking me out w/its weirdo wobbling

MATH ADMINISTRATOR this shit is totally unfair
― ice cr?m, Wednesday, 17 December 2008 18:31 (fifteen years ago) link
look at it: 2x^2 + 2x - 12 = 0
forget the = 0 for now
=0
ok so u know it's a quadratic being factorised, hence u shd already have the following in mind
(2x...) (x...)
a bit of trial and error shows us that
(2x-4) (x+3)
multiplies out to give the initial equation
when (2x-4) (x+3) = 0, one of 2x-4 and x+3 must = 0 too. hence x is 2 or -3
thank u

all you need is to be a half-decent australian/south african club cricketer, then to apply to Oxford Brookes University to do Business and Management Studies, then you automatically get into Oxford University Centre of Cricketing Excellence side :) hope this helps

the moon is always showing us the same face, which means that sunrises are separated by the amount of time it takes to go round the earth (i.e. 28 days). maybe draw a diagram if this is difficult to imagine.
lj has kinda the right idea for why it shows us the same face.
