lol damnn which parts?

in da 3U lost a mark in MC BY INPUTING THE WRONG NUMBER INTO CALCULATOR

Am I the only one who thought it was easier than last year? lol maybe it just had more tricky questions i suppose like that circle geo (maybe it's cos there are only 3 marks of probability which i suck at :P)

Re: HSC 2013 3U Marathon Thread Wow GENIUS !!!

Ahahahah binomotion

holy crap top mark 65/70!!!!

Re: HSC 2013 2U Marathon add 1 and subtract 1 :) start by using limiting sum of 1+ cos+cos^2..... and the same for 1+ sin + sin^2 this is allowed since the ratio sinx is between -1 and 1. same for cos x.

nek minnut, carrot sticks actually wrote the HSC paper consisting of generalized questions

I reckon, this isn't normal at all!!!!

Re: HSC 2013 2U Marathon Correct me if I'm wrong but I think the limits of dat integral is meant to be from b to a and not a to b

Re: HSC 2013 2U Marathon is it 95/2? EDIT: whoops miscounted is it 91/2

Re: HSC 2013 3U Marathon Thread isn't it ln(x)/(1+x^2)? Cause I can't seem to get 0 with your integral lol

Re: HSC 2013 2U Marathon Lol whoops forgot about the 1/2 at the front of the bracket, (sigh I forgot about trapezoidal rule )

Re: HSC 2013 2U Marathon it's funny cos he somehow got the right answer with some errors in the working

Re: HSC 2013 2U Marathon for part ii) I got \int_1^n \frac{1}{x} \ dx + 1 + \frac{1}{n} < 2\left(\frac{1}{1} + \frac{1}{2} + \dots + \frac{1}{n} \right) \ \ \ \fbox{3}

Re: Chess thread? dude can you like PM me the link instead lol

Re: Chess thread? aLright let's try again :)
