f''(x) = 0 , remember to show a change in concavity as some schools deduct marks for not showing it

Since it's a hence question you would have to relate it to part b). I would have assumed that there was a common root. So if a root of g(x) is a root of f(x) [let's call the root 'a' from now on], then g(x).q(x) would have to equal zero Since we have assumed that 'a' is a root of f(x), then...

Re: Fairfield Troung's recommendation - English Ms Diab is an awesome teacher :D. The chances of joining are slim due to the size of the classes as you've mentioned. If you want to join at Canley Heights/Fairfield, apparently you also have to go to maths/science there too.

These holidays have been alright. I've been out a few times and got a head start on on the HSC course. Despite that, I haven't done nearly as much work as I would have hoped :(.

LOL. I never got mine either. Discrimination against those who cant write without lines :p Haha, yeah I did, it's a few post back

Yeah, context is probably your best bet. Conquering and Jacaranda aren't so bad though. It depends on your personal preference, I guess.

That's actually pretty neat :), well I think so. How do you write in straight lines on a blank sheet of paper o.o .. Whenever I do.. my writing tends to creep to the top of the page, or to the bottom depending on how it's feeling ._.

page out of my maths book =x http://img379.imageshack.us/img379/320/scan0006my5.jpg

They're past catholic paper questions.

LOL. whoops. That's what I meant. x).

I like maths :), except when I make too many translation errors, cause that just makes me sad :(

oh hey. x). Thanks tommykins,3unitz, lyounamu and Iruka :)

Re: 回复: Polynominals. Ah. I think the question meant 2 distinct zeros =/. For 2, I'm not so sure what you mean by 'change in sign' :( sorry but could you explain it again? Don't worry if you're too tired though :). Thanks :).

Um.. Just a few polynominal questions I can't do. Hope you guys could help :). Thanks in Advance. 1. The polynominal (a-2)x2+(b+7)x-(c-8) has 3 distinct zeroes. What are the values of a,b,c? 2. Show that the equation 2x3 -3x2-7=0 has at least one root in the interval 2< x <3 3. Given...

Dotpoint is more of a summary book where you answer questions derived from the syllabus. The quality of the book depends on how efficiently you utilise it, whether you answer the questions with reference to other sources before consulting the answers as opposed to relying on the answers at the...

haha. Yeah i was considering getting the new one, but then i decided not to due to excel's poor reputation :(. I'll probably end up purchasing dotpoint from my school for $20-25 Oh dude. Someones prepared. *worried :(*

Just one of the things i've gotta try :)

Easyway ain't cool anymore.. :( as if 5 bucks.

Ah, so from what I've read, I'm guessing Heinemann and K.I.S.S will be sufficient for year 12 bio?

Development of the Periodic Table Johann Dobereiner (1780-1849) In 1829, when 40 elements were known, Dobereiner noticed that these known elements could be grouped in groups of 3, Triads. · These triads shared similar physical and chemical properties o Chlorine, Bromine, Iodine...
