sorry if that's hard to read, idk how to latex

first note 1+x+x^9+x^10 = (1+x)(1+x^9) then we split the integrand into x^2ln[(1+x)(1+x^9)]/(1+x^3) = x^2(ln(1+x) + ln(1+x^9))/(1+x^3) now we split the integrals up so we have integral from 1 to 0 of x^2ln(1+x)/(1+x^3) + integral from 1 to 0 of x^2ln(1+x^9)/(1+x^3) Then we do a u =x^3 for the...

ya but the question says it's not

seems pre legit

this is not the correct approach tho, since Hclo4 is a weak acid [clo4]- is a weak base, thus Naclo4 is in fact a basic salt which u ignored in ur working

i didn't attend but no

the complex was rlly easy but the mechanics was little goofy

last yr's was easier imo

highest

record might be broken👀

I agree that the questions are easier for physics in general but for good students I feel it is typically easier to get higher in a maths x2/x1 paper than a physics paper due to specific aspects of the marking criteria that can be easy to miss amongst other things (given the papers have...

Thanks! I was asking about time management because my time-management isn't very good since I get distracted a lot by external factors such as social media and youtube.

Over the past few yrs, it's been around high 30s - low 40s chem b6s, 60-70 ext 1 b6s, high 20s -low 30s ext 2 b6s, ~30 physics b6s and typically around mid 40s english advanced b6s

Hi all, can I please have an Atar prediction (and also some advice on how to best organise my time from now to hsc since my time-management is rlly poor) I go to a top 10 school Chem-5/83 English Advanced- 21/134 Maths ext 1 - 3/98 Maths ext 2 - 1/50 Physics - 2/73 Tryna go for state rank...

why is a, b, c being less than 1 a problem tho cos ii is true for all positive a, b, c

yoooo

sr ext 1 is pre much rng I wouldn't recommend grinding for it

errrr since it's given that Sn = 0 if n is a multiple of 3, gp isn't needed. instead u can do w+w^2+...+w^3k + w^(3k+1) = 0 + w^(3k+1) = w and then do the same thing when sum is to 3k+2

🤔 x^3-1

it worked well for me in maths but idk about subjects that are more memorisation heavy such as eco or business. I feel like u might tend to forget quite a lot of the content that you've learnt.
