but it just says which one will always be positive Edit: just realized how math worsk 3x3=9 oddxodd=odd evenxeven=even evenxodd=even i was thinking of (-x-=+) (and +x+=+) there goes another mark

And for the question 30 Did anyone just guess when Cos(x)=sin(x) in there calculator i found 45 degrees converted it to radians got pi/4 then added 4pi/4 to it

i did the rough mark and i probably got about a 60% on that exam, my biggest mistakes was trying to find the area bounded by the two curves and y axis and i only just realised i didnt have to make x the subject but could of just put the boundaries of the x value instead of find the y intercept...

Can someone explain why this sheet say question 9 is not c isnt (even)^2 and (odd)^2 even regardless

i had to double check on that i almost left it as a percentage but change it to numbers of koalas, almost lost a mark

Damn i tried learning how to find area bounded by the y axis, and you have to make x the subject, but there should of been a better way to find the area of that one question i did like Integral (2lny-lny/2x) or some crap you have to show the area equaled 1/2 (ln2+1/4)

Yeah i roughly got a 95/100 on 2022 but only 70 for 2021

I have hospo in 11 days and chem in 12 but i wont care to study hospo, easiest shit in the world. what im worried about is the physics one 5 days after while also having pdhpe between the two, practically 3 days for physics and 6 for chem

never mind i had a minelapse (x^m)(x^n)= x^n+m not x^nm damn i can do calculus but cant do basic indices

This is what i got but i should of clarified that i dont know how (r^2)(r^n-1)= r^n+1 doesnt it equal r^(2n-2)

I'm just about able to do most of the maths adv HSC exams from the new syllabus without requiring help, except the last question of the 2021 paper. How does everyone else find the question?? apparently the overall knowledge you require is E(x)=1 ,and E(X)= E(xP(X=x)) Edit: the thing i dont...

Maths Adv + Ext 1 (I dropped out of Ext 2)

Ok look ive put in 30 hours of study for maths in the last 6 days and about 3 in English last night, i got 40% for my trials i just dont have an aptitude for english and studying wont change that. Good luck on your exams

Man i dropped out of Extension 2 after term 2, have fun with your mechanics

I just hope there won't be any 7 or 8 markers on Solubility, or identifying anions I'm terrible at those all i know is all group 1 metals plus ammonia is soluble in most things
