Gee. That paper was the hardest I have ever done. Seriously. Not looking forward to MX2.....

Good questions guys. I will enjoy doing the MC and core sections of the paper. Is anybody willing to write the industrial chemistry part?

Carrot, can I attend too please?

LOL. I honestly think he wouldn't have a problem if it wasn't with respect to v.

Didn't Jeff Geha do something similar? Get 100% or close to it in 4Unit?

This. I really doubt BOS is going to put a resisted motion question as a MC question that is normally worth 2-3 marks.

we use all of them at school (except Patel + Terry). From experience, I find Fitzpatrick OKAY for learning the basic concepts (some questions are on the weird side though). However, for consolidating on learnt knowledge, no doubt Coroneos is the best. Stay away from Cambridge as much as...

what does the weird pi like notation mean?

lol really? Our school doesn't bother. There is no point. :S

You'll have to do it in two parts: The first part: you consider the shells made between y = 0 and y = 2. They will involve ONLY the line y = x The second part: you consider the shells made between y = 2 and y = 4/3. They will involve both y = x and y = x/2 + 2. Then you add the two parts...

honestly said, a better practice should be that they give you a separate copy of the diagram for you to work on. Makes life much much easier.

I have no idea how to attempt part ii) of this question. Anybody care to give me a hint/tip?

no need to find angle AGO. you can find angle AGC directly from exterior angle of triangle theorem (angle OAG + angle AOG = angle AGC). :)

Following on from RishBonjour..... Expand the RHS first using binomial theorem (ie. the first term). Every term in the expansion would be divided by x, so the general term becomes n+1Ck times x^(k-1). From here, consider the term in x^2 on the RHS: ie k - 1 = 2 therefore, the value of k is 3...

already gave an official appeal. What do they normally do in these sorts of situations?

How can i have multiple values? I think what you meant to say was 1 <= n < 7 =)

don't worry man. My idiotic teacher puts a question in our trials from a topic that we didn't even cover in class. AND she even said it wasn't going to be included in the paper. 8% gone then and there. :|

That question. WTF. :S

lol our cohort size is like 350 people. Beat that.

Re: 2012 HSC MX2 Marathon Alright, I'll have to think about it then. :S
