Re: HSC 2012 Marathon :) cmon, change it to sum to product as well

Re: HSC 2012 Marathon :) nope, nothing but trig :D

Re: HSC 2012 Marathon :) Ok here is another question. Prove any product-sum or sum-product trig ratio from the startpoint of sin(x+y) and sin(x-y)

Re: HSC 2012 Marathon :) yeh, that is correct. The question was aimed at just testing the understanding that simpsons rule uses parabolas to estimate that is all :)

Re: HSC 2012 Marathon :) oh yeh whoops...

Re: HSC 2012 Marathon :) whoops, sorry it was supposed to be x^2 - 3 haha

Re: HSC 2012 Marathon :) different constants, as the restricted domains of the original functions vary by pi/2 simplify the following trig expression. sin(x)+cos(2x)+sin(3x)+cos(4x) damnit that doesn't even come out good at all. Here is a conceptual one :) Find the volume created by...

Re: HSC 2012 Marathon :) find the inverse function of. and state its domain and range <a href="http://www.codecogs.com/eqnedit.php?latex=y=e^{4x}@plus;5e^{2x}@plus;1" target="_blank"><img src="http://latex.codecogs.com/gif.latex?y=e^{4x}+5e^{2x}+1" title="y=e^{4x}+5e^{2x}+1" /></a>

Re: HSC 2012 Marathon :) 1 lol

holy jesus

k sweet :D

you could also discuss MC briefly, but i guess nobody really knows that anyway

mate, negging me back is unfair cos u have more rep power

hopefully :)

done 10 yet? :P

Re: Official BOS Study Meat v2.0 i will connect in by video link guys haha

who is this?

Nah, what i mean is that ATAR is not a direct percentile, as it is skewed so only about 9% or so get less than 30. Therefore they have to put more people per rank than there should be for an even percentile distribution. Hence why more people get that atar than the percent.
