oh my bad, what i sent was for mod 5
i dont have much resources for module 6 at the moment (maybe it can still come in handy when trials come around )

 

[f7eeting]

I'll trade you mod 6 recourses for 3u resources later
I just remembered how much I hate ksp and common ion effect

thankfully 3u is the one subject i have an abundance of resources for

 

[f7eeting]

@ALolly or @f7eeting
Does the formula:

(n/6)(n+1)(2n+1) appear in adv specifically acting as an "integration by first principle"?
It pops up in mathematical induction which is an 3u topic so for 2u is it just an unnecessary proof?
Am I overdoing this?

can you show me the question so i can see how its being applied?

 

[f7eeting]

Ignore the messy handwriting I'm watching a video and jotting down notes

messy? you should see my handwriting lmao. anyways ill take a look at it now

Yellow green and the next page. It's boxing in the integral

okk i see what you're doing but i don't think its necessary to understand the sum itself (1^2+2^2+...+n^2=(n/6)(n+1)(2n+1)) and how its derived bc i think that can only be done through mathematical induction

so dont worry about it

 

[f7eeting]

Oh I will understand how it is derived I just wanted to know if I'll get penalized by doing stuff like that. Thanks!

ohhh well no because its perfectly fine to use stuff from the ext 1 course in adv so you wont get penalised.
even the hsc has out of syllabus answers considered as valid so it should be fine

 

[f7eeting]

YESSSS I can finally deal with factorising those cubic without guessing!

may i ask what your method would be without guessing?

 

[siennabou]

- solid work for today
8/2/26
- complete 2 hms questions
- english grindddd

 

[f7eeting]

Finding the roots which I can add to my list to learn. Hence why I was going to ask you for revision material on all of this. For my plan all content for all subjects must be finished no later than week 5 which gives me time to go back to previous modules as well as clean up the stuff I skipped on the year 11 ext syllabus and hopefully do 1 topic of year 12. That means my holidays after hsc can be used to practice instead of learning and hence I still get to live my best life whilst not going to university and having a replay of year 10

damn well if you ever need material or somebody to teach you i can help (except for perms and combs........)!
i think you can learn all the ext 1 content pretty easily tbh and within a pretty short span of time.
i lowkey didnt understand anything about yr 11 ext and was about to drop it until a few weeks before prelims when i locked the hell in and somehow learnt everything and managed to get 2nd highest, so im sure you can do the same too lol

 

[f7eeting]

Providing I actually get a good atar and not smt like 70 or 80

trust me you're guaranteeeddd to get an atar above 90!!!

 

[f7eeting]

And its the most useless branch of math either way

yeah it is really useless lmao but i guess it did push me to think in a way i hadnt rlly done with other topics

 

[f7eeting]

Can you tell me what to start with for the year 12 syllabus? I have a few year 11 exercises scattered around but I really don't think they will be full on assumed knowledge level.

induction id say is worth learning, it is mainly just algebraic manipulation buttt it does introduce you to how to structure proofs and also can help with getting familiar with sums.
also vectors!! its a very important topic especially if you're looking to do mechanical engineering
also learning ext 1 integration should also put you in a very good position for uni

 

[f7eeting]

haha I'm not sure about a short span of time. Mostly I'll only be doing bits of ext on weekends when I'm not super locked in for my actual subjects. I kind of want to see what's in ext 2 but I'll deal with some more of ext1 first.

ext 2 can be suchhh a pain but when i tell you its the most rewarding subject ever!!
i think its worth looking into complex at the very least, its a very nice topic and ive heard its also in a lot of university engineering courses

 

[f7eeting]

That's tbd still. I've heard vectors are really hard....

vectors can get pretty tricky at times and it took me a while to get the hang of it but it ties into soo much other topics, so understanding it is definitely worth the struggle

 

[f7eeting]

*ahem* electrical and aerospace

yeahh complex is very very useful in electrical and aerospace engineering!

i dont think ill be doing either one of those courses tho lmao but who knows

 

[f7eeting]

Electrical is seen as torture and aerospace, i haven't heard of insane employment inside of Australia

yeah ive heard of that too, its a shame, i wouldve liked to go into aerospace but i really dont plan on leaving australia

 

[ALolly]

today:
more hms ( i hope i can actually finish it today without getting distracted)

 

[Study to success]

Today:
Finish indefinite integrals
Finish trig eqn&graphs
Do some of my English primary draft

extra work:
Gain the fullest extent of confidence in pH calcs
Continue on with 5.1 physics calcs
Figure out what on earth I'm actually supposed to study for art

I feel like we need to start a major work accountability thread cause I procrastinate so much on that stuff especially cause it isn’t like something like math where u know exactly what u need to do ykwim

 

[Study to success]

today:
- Finish my justification for primary research methods
- Work on DT: the stuff I was supposed to do yesterday

 

[f7eeting]

today:
chemistry
- more mod 5 review

math
- attempted questions from @ChromeDragon26 (very fun)
- vectors
