Actually guys bos works now on school internet

 

[Study to success]

BOS keeps crashing. I don't think it was the school though.

idk. but when I came back home that's when it started working

bro in society and culture we get 5 and 15 markers instead of 20 markers and we also get 9 markers instead of 10markers cause for stuff 10markers+ need to be marked twice and they want to save money.

2 weeks of school finished, and this has already gotten boring. Why can't we stay home school is practically useless

this is how i feel every time i have english

 

[f7eeting]

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?
