Re: Official BOS Study Meat v2.0 meet box FTW this is why you guys should come to Usyd (jks, eating a meatbox is actually quite time-consuming, not very neat either, regardless of its health effects besides, I'm not even going ) from what I read in the library's website, there'd be...

Re: Official BOS Study Meat v2.0 I'm plagiarising your latex code: \forall \forall, \exists \exists PS: mathematicians are not very good at making jokes

Re: Official BOS Study Meat v2.0 as far as I can see, there are quite a few people helping with maths so I'd guess we may need more tutors in other subjects

Re: Official BOS Study Meat v2.0 http://www.parracity.nsw.gov.au/play/facilities/library/about_library/facilities#lib_meet are these 3 meeting rooms the ones you're talking about?

since x=3/2 is a double root, then P(3/2)= (3/2)^4-2(3/2)^3+c^4=0 ,we'd get c^4=27/16 [I expanded everything, P(x)=x^4-2x^3+c^4] then P(x)=x^4-2x^3+27/16 has a double root x=3/2 let the other 2 roots be a and b a+b+3/2+3/2=2 ==> a+b=-1 ab(3/2)*(3/2)=27/16 ==> ab=3/4 so a...

thanks for reminding me it doesn't always have to be a double root, but the multiplicity must be even for example, f(x)=x^4 but in this case, it just happens to be a double root (since quadruple root doesn't work, and it's a quartic)

but I think you'll need to justify why it's only a double root not triple, or quadruple [find P'(x) , P''(x), P'''(x) ] PS: it could only be either double or quadruple, since they're touching

the black one is the actual graph if it's a single root(red curve), then it must intersect y=0 again, giving us another real solution, condradicting the fact that there's only 1 point where they touch

solve simlutaneouly , as suggested by 4025808 you'd obtain the quartic in the question circle TOUCHES hyperbola implies that there is a real solution that's a DOUBLE root EDIT: it's doesn't , see #11 then from your graph, you can see that point must the be ONLY place where they...

is it just me , or you can't really see the question clearly?

Re: HSC 2012 Marathon :) what I picture in my mind when I see the word 'ladder' when was the last time you've seen one of these: I guess one could make a somewhat a variation of the question, using the 1st one

Re: HSC 2012 Marathon :) maths teachers NEED better ladders

try http://www.mediafire.com/ or something similar

Re: Official BOS Study Meat v2.0 travelling overseas during the Winter Holiday for university students (which coincides with the upcoming school holiday) So I guess I'll probably join you guys next time and thanks for Carrotsticks organising this event

Re: is there any double angles or stuff such as sin(x+y)=sinxcosy+cosxsiny in the 2u http://www.boardofstudies.nsw.edu.au/syllabus_hsc/pdf_doc/maths23u_syl.pdf P40

obviously, MX2 is quite different from MX1 in terms of both course content and the difficulty of exam questions one might argue that you may end up with a higher scaled mark(thus ATAR as well) in the end even though you might not be as confident in your understanding of the subject And I...

I'm currently unavailable... but I'm pretty sure that there are many excellent tutors in the aforementioned area

Re: 2012 HSC MX2 Marathon why not?
