With this question, I'm wondering how this is in the syllabus as how are we supposed to know what Faraday's law is (That is if the answer of D is true). I figured it was either C or D but if its not in the syllabus how are we supposed to know the answer. Just curious really

Re: General Thoughts - Maths Extension 2 I think it was comparable to last years in terms of difficulty but still a lot easier than previous ones. Hopefully i managed >105. Also why was there so much conics if they are planning to get rid of it. I thought it would have been the other way round.

probability of getting a sum of 7 is 1/6 therefore 4C2*(1/6)^2(5/6)^2 + 4C3*(1/6)^3(5/6)^1 + (1/6)^4=19/144 (hopefully) (I don't have a calculator on me but im pretty sure its right)

I got 94/120 (78%) and i don't think that i'm close to the top of the state, well not yet. I'd think you would have to get like 95% to get close to the top. As for band 6 i really don't know but i think the CSSA trial this year was not as hard as previous tests.

Well this is good but they would be much better with some solutions.

I got 87%. Fairly happy even though i didn't go too good in the option.

i agree

I'm pretty sure i got something like that as well

It wasn't too bad. I couldn't do much of question 8 but wasn't really expecting to. Hopefully 90/120

Wow. that was fairly difficult, especially the binomial in question 7. I reckon that was much harder than past CSSA papers.

I couldn't agree more. It is definatley the worst.

I only listen to music when im doing maths cause i figure if i can do the question with the music on, im pretty sure i can do it with it off.

I've never used one but i've heard of them. (http://www.grand-illusions.com/acatalog/info_48.html) Or you could get a space pen, apparently they last a long time.

Everyone should get the inkless pens that last forever and you will never have to buy a pen ever again. ;)

Don't you just 'get rid' of everything below the x-axis and then reflect the rest of the graph in the x-axis.

Actually 'helper' I think they are different rules but I’m pretty sure you don’t need the left hand rule cause only the right hand rule is in the syllabus. Also there’s the right hand grip rule where in a current carrying conductor your thumb points in the direction of the current and your...

I think this is what jemsta was talking about: http://www.boredofstudies.org/scaledmeans.php Even though it is from 2003 Latvian Continuers seems to be the highest.

yeah i thought it would be 4cos@, 3sin@ as well because isn't @ just -pi <@< pi

Anyone? I'm sure a lot of you have done these questions before.

We have inverse functions to go.
