MIF - ? dont they only produce books for the idiot course......?? errr........ahhaahah jkz

you should do the idiots course mate, they learn quad formula there ROFL~@!?>@!?.no.

lol im sorri? was that post in reference to some other thread?

idiot course = general ...right?
hmm well in response that - my friends pointed me to this prelim general textbook the other day and were laughing their heads off. (so inconsiderate to those general pple *sigh* ). yes what they found so humourous were the questions:
such as -> 1. what is this shape?
2. what fraction of this shape is shaded (towards the end of the book)
and i admit it was quite funny. apologies to all maths students.

they suggested that i drop down to general coz i suck so much - so that ill get 90s. ahah pfft

on a more serious note, im looking for a good 1-to-1 maths tutor. priority is CHEAP (15-20$/hr). preferably a gurl (hahaha).

 

[Li0n]

gee different people have different mathematical abilities?
its not their fault they dont have as developed abilities as other people do.

textbook...

we are currently using the classic Couchman Jones 3 unitmaths text in class.
what do u pple use??

i feel that this book is quite outdated (my maths teacher used the book himself, in his HSC) and does not realli have the harder questions to truly challenge students. It is, i have heard, actually the easiest book out there in use by skools.

im thinking about getting the harder texts for year 12...Cambridge or Coroenos.

we use Maths in Focus, by Margaret Grove. our teacher also photocopies stuff from the Jones and Couchman. for harder questions we use this small one by a guy called Fitzpatrick, which is quite helpful in exam prep.

ooh... so Fitzpatrick is small...
well the only ext2 book ive seen is cambridge and its small
i just didnt think that other books are small too.

 

[Li0n]

only ext-2 cambridge is small
ext-1 prelim and ext-1 hsc cambridge are heavy fuckers.
and cambridge ext-2 is stll big compared to that cornease ext2

 

[Estel]

But there's 2 of em

re:

I'm thinking of buying the yr11 Cambridge...except I havent touched couchmann....

Cambridge is worth. It is better than New Senior maths as i know. NSM is good at explain, but cambridge is good at practising. Using both of them, you will find they both are useful, but cambridge will be much better, though.

Hsc 4u

only ext-2 cambridge is small
ext-1 prelim and ext-1 hsc cambridge are heavy fuckers.

I am not using cambridge for 4U, 3U only, nothing to do with 4U cambridge, But i heard that the auther is not very good, but......... ummmmm, how is that book, but excel 4U is particularly good. All my classmates use it. It is complusory for all the 4U students in my school.

the authors are smart people
Denise Arnold and Graham Arnold,
hence the term Arnold & Arnold

it's better than NSM in some aspects.. worse in other aspects.

 

[zergcave]

im NEVER buying ANY book from the EXCEL range EVER AGAIN.
every author from excel is shit to the MAX. some classic example would include neville warren (physics), and jeremy b. (economics).
the physics prelim - simply goes on and on until it gets to some point. written in the sense of a story :S. especially not good for revision. lame.

Maths is also SHIT. hardly any explanation at all

 

[Li0n]

buying prelim books is such a waste of money

Re:

yeah, ummmm.......Let me tell you. Excel for 4U is absolutely useful. Believe me. Once you use it, u will love it.

I used it. I didn't love it. But then textbooks have never really done it for me, especially in 4u, because I find the explanations to be inadequate, so I just go blindly into the questions and mess around until I get the right answer, then remember the method I used for next time.

STICKY THIS THREAD!

ffs, people ask this ssoooo damn much, it's not funny.
PLEASE. this thread is as good as any of them.

 

[mishka]

as told earlier, we use couchman...

now i have never gotten around to working out how to do integration by substitution until now (daydreaming in class, i think!). but the MIF book has been really helpful so now i don't groan when i see one in a past paper!!

 

[Slidey]

you should do the idiots course mate, they learn quad formula there ROFL~@!?>@!?.no.

That's something like
y=ax^2+bx+c
lety=0
0=a(x+b/[2a])^2-b^2/[4a] + c
a(x+b/[2a])^2=b^2/(4a)-c=(4a)^-1 * (b^2 - 4ac)
(x+b/[2a])^2=(2a)^-2 * (b^2-4ac)=(b^2-4ac)/(4a^2)
x+b/[2a]=sqrt[(b^2-4ac)/(4a^2)]=+sqrt[b^2-4ac]/[2a]
x=(-b+sqrt[b^2-4ac])/(2a)

Dammit. It is a lot easier to complete the square on paper.

I'll ask Laz

EDIT: Stickied. Thanks Tactic.

lety=0
0=a(x+b/[2a])^2-b^2/[4a] + c
a(x+b/[2a])^2=b^2/(4a)-c=(4a)^-1 * (b^2 - 4ac)
(x+b/[2a])^2=(2a)^-2 * (b^2-4ac)=(b^2-4ac)/(4a^2)
x+b/[2a]=sqrt[(b^2-4ac)/(4a^2)]=+sqrt[b^2-4ac]/[2a]
x=(-b+sqrt[b^2-4ac])/(2a)

Dammit. It is a lot easier to complete the square on paper.

When asked to prove quad formula I just work backwards.

 

[Slidey]

(2ax+b)^2=b^2-4ac
4(ax)^2+4axb+b^2-b^2+4ac=0
4a(ax^2+bx+c)=0
ax^2+bx+c=0

I guess it is a bit easier.
