... i think someone has inferiority complex issues...

Its all here - http://community.boredofstudies.org/14/mathematics-extension-2/125560/comparison-maths-ext-2-books.html lolz!!!

Yeh, i also though that question 3 looked wrong to me.

1 + (1+x) + (1+x)^2 + . . . + (1+x)^n = \frac{(1 + x)^{n+1} - 1}{x} test for n = 1, LHS = 1 + (1 + x)^1 = 1 + 1 + x = 2 + x RHS = \frac{(1 + x)^{2} - 1}{x} = \frac{(1 + x + 1)(1 + x - 1)}{x} = \frac{(x + 2)x}{x} = 2 + x \therefore LHS = RHS assume true for n = k 1 + (1+x) +...

\sum_{r=1}^{n}r(2^r) = (n-1) 2^{n+1} + 2 test for n = 1, LHS = 1(2^1) = 2 RHS = (1-1)2^{1 + 1} + 2 = 0 \times 2^2 + 2 = 2 \therefore LHS = RHS assume true for n = k 2 + 8 + . . . + k(2^k) = (k-1)2^{k+1} + 2 prove for n = k + 1 2 + 8 + . . . + k(2^k) + (k + 1)2^{k + 1} =...

They are in the Maths Extension 2 forum, here http://community.boredofstudies.org/14/mathematics-extension-2/167303/full-cambridge-fitzpatrick-solutions.html or, if you want to look, its the 3rd thread down!

If you think you are passionate about economics, then why not do distance education. It takes some time to get used to the sitting down and doing it, ie independent learning. But i should get better. If you don't like how distance education is going after 2 or 3 weeks, just go back to chemistry.

Okay, so you have done everything right, you just need to factorise in order to simplify. You have u = x u' = 1 v = (x + 1)^3 v' = 3(x + 1)^2 As you know \frac{dy}{dx} = u \frac{dv}{dx} + v \frac{du}{dx} therefore \frac{dy}{dx} = x \times 3(x + 1)^2 + (x + 1)^3 \times 1 = (x +...

No. Most of Geometric apps of calculus is differential, but in saying that, in my schools text, there is a little exercise on primitive functions which would help a little. But besides that, the integration chapter is easily accessible without the geo app.

congrats! :)

Okay guys, i have made some progress! A friend of mine, a teacher, was wonderful in such that she helped me heaps with this. I went with the suggestion of writing a letter / proposition plan for my acceleration. Essentially it boils down to this: I will be siting on all the HSC mathematics...

What?! This seams completely ridiculous! There is no way that the school would suspend half of the students! How would classes work! They would make front page news! Show me the rule that says you cannot have a day off :)

Mine has 8 :P

this is hilarious!!! real lol

yes, i am in year 10 and have frees!!!! See, the year 11 maths classes (adv and ext 1) happen to be when i have certain optional topics such as commerce or IT, and also, my years year 10 maths class is run on a different time (line if you will), so i have free when i have maths as well as 3...

I would first like to say that i do not want this thread to turn into a brawl. I merely want to voice my opinion, and give others the chance to share their opinion on this particular topic, whether for or again it; a mere medium for discussion of students views. I understand that the BOS or...

Thanks, do you know if you have to be in the classroom for the prelim or HSC? See, i think i have fell into another trap door! When prelim extension 1 mathematics is on, HSC advanced is on (thats this year)! Do you have any suggestions?

Thanks heaps for this namu :)

Just to clarify for you, my 'real' school year is year 10. Now i accelerated into year 10 maths when i was in year 9 (ie last year), then i just progressed into the year 11 adv and ext 1 classes this year. I am only doing year 11 adv and ext this year because that is what was allowed by certain...

And also, namu, the person who does timetable stuff or whatever (generally he has a say in acceleration), said "In order to start the HSC, you would have to have completed 12 units of preliminary..." and this was in reference to my suggestion. Well, i had a think about this, and it is completely...
