they r so trash

question- where did u guys go for retreat? im going this wed, just curious

 

[siennabou]

I would say if I knew what that was at first

like dont u go on a camp for year 12?

 

[siennabou]

I believe not. The last time was year 10

oh fair enough then!! my school takes us on a final trip Lol

i just sucked @parmesean's nice cock

Lake maq. But mine is in term 2

@ALolly Did you explicitly go back and study year 11 for content hsc at any point for math adv?
Did year 11 questions come up or was it more like year 12 questions with parts that required year 11 skills?

i went over yr 11 for trials and hsc cuz for maths especially year 11 content is assessed in the hsc and trials. if you look in the mapping grid you'll realise that a couple questions are year 11 stuff

 

[ALolly]

Can you please tell me what that is?

like scroll all the way to the bottom of the marking criteria and there is a mapping grid which tells you what questions are from what topics and you'll see that some of them are yr 11 topics

@ChromeDragon26 for the integral you sent yesterday, what am i supposed to prove?
am i supposed to get a certain expression out of the integral?
or do i just use a riemmann sum and find a way to sub in the given sum then simplify that?

 

[ALolly]

Ah yes thanks most of it is year 12 but I should spend a week or 2 on year 11 stuff after AT2 concludes

yea probs

@ChromeDragon26


this took me so unnecessarily long but I DID IT!!! also i had to evaluate the limit on the side bc i didnt wanna start a new page

 

[f7eeting]

Tbh you can skip the first bunch of steps as it's all just for show
Its easy enough to get to the conclusion of the sum of upper and lower rectangles then only thing is sub into the given formula and prove it. And lmao we aren't ever getting a question like that its out of scope even in 3u and 4u until next year but its fun so I can't argue

well it looks nice so i dont mind the extra working haha
also damn its not even in the scope?? at least it was really fun to learn

 

[f7eeting]

I need to improve my speed so much that took me like 15 minutes....

it took me an hour to figure out what i was doing... i now realise just how little i really know about integrals

 

[f7eeting]

It's easy when you do it a few times and figure out that everything basically works the same.

This is the next thing that I have to figure out its so cooked

damn that looks really hard
i only recognise the (1+1/n)^n formula because thats one way to express e if u let n approach infinity

 

[f7eeting]

wait im gonna attempt it for fun. cant say i'll get very far tho lol

 

[f7eeting]

I can't even make sense of it I need to see the steps thats a 2002 cooked ahh hsc question

2002? that questions older than me lmaoo
also my knowledge on integrals is so cooked i cant even integrate 1/x with the knowledge i have rn

 

[TheEliteTitan]

Lord help me
I feel useless I. Front of these smart iddiots
Where tf did you find that question tho

 

[f7eeting]

Lord help me
I feel useless I. Front of these smart iddiots
Where tf did you find that question tho

trust me you're probably smarter than i am

 

[f7eeting]

I FINALLY GOT THE QUESTION
It's actually easier than the last one it just looks way more cooked. Only thing is that I came across some algebraic manipulation i've never seen before but other than that it was ok.
View attachment 51580
It's not toooo bad only comprehending the question was full cooked

ohhh that e^lnx thing is really smart, thats where i got stuck ill reattempt the question later

 

[beetard]

oh fair enough then!! my school takes us on a final trip Lol

is it like the nsb study camp thingy
