Bet I will tmr

soooo about this
i got bored in math adv today and quickly did the proof, if you get to it i wanna compare our working

Why is it important to neutralise oil spills ?"

this isn't a chemistry question .

imagine if math exams asked "why is calculus so important to daily life"

man fuck the nsw syllabus

 

[f7eeting]

A question was "Why is it important to neutralise oil spills ?"

i got a question similar to that in my chemistry exam today, i think i dropped a mark or 2 bc of it

 

[f7eeting]

Oh how was the exam?

it was fine, but there were some questions where im unsure if i did them correctly.

 

[f7eeting]

Oh yeah and when proving that root 2 is irrational what are the prerequisites? I want to actually learn it instead of copying someone else's working out.

theres no real prerequisites
id say the most important thing you need to know is what a rational number is even is defined as, and let that definition be equal to root 2
then go from there
another thing that may be helpful to think about is what does it mean for a number to be even, and what even numbers really are in their simplest form

the nice thing about proofs is that they make you think about math from its veryyy foundations, so its not really anything new

 

[f7eeting]

What book do you use?

cambridge

 

[f7eeting]

from the perspective of an average person of some obscure ext 2 proof

welll okay you can look into 'the language of proof' which is an ext 2 topic- it might be worth briefly looking into the different sets of numbers, such as rational, integers, natural etc
and also looking at what even/odd numbers and integers can be written as at their simplest form (its all simple stuff so dont worry)
then look into the method used for proofs by contradiction

then hopefully you should be good to go?

 

[f7eeting]

Wait is it complex numbers?

what do you mean?

 

[f7eeting]

what are the main topics I must look at?

its in the topic of proof. if you're looking in the cambridge textbook, id say to skim over chapter 2B (number proofs) and most importantly 2C (proof by contrapositive/contradiction)

 

[f7eeting]

Which hopefully don't take me a week to learn

not even joking, you could learn it in half an hour.
anybody that has basic algebra skills could do this in half an hour. im telling you, its super simple. genuinely

@f7eeting I trust that this won't be me 10 seconds after I look at the chapter right?

7:30 on a Friday night and I am here researching Arthur M. Schlesinger Jr for Extension History

 

[WTbattleace]

History on a Friday night is a vibe. There is no better subject for a time like that. Also, I'm curious, what do you want to do after high school? You are literally maxxed out on English and history so don't tell me you are going to do something else in the complete opposite direction.

My dream course would be to do a BSecStudies at Macquarie. After that, I want to join the AFP or get into politics.

omg another history ext student
i'm completely fucked i still haven't locked in a topic
i just cannot find one that 1. doesn't clash with the syllabus 2. has enough sources 3. i can get a question or five out of

You talking about the major project?

 

[WTbattleace]

I have settled on the Black Wars in Tasmania, and the historiographical discussion on genocide, looking at the contexts and political motivations of Keith Windschuttle, Henry Reynolds, and Lyndall Ryan.

Also, what is your case study? My school does JFK

Pretty sure mine does too. How many students are in your class? There are 3 inc. me at my school so not many at all
