yep, (pi x sqrt3) / 6 did it ask for 2dp? if it did im fucked.

I used similar triangles.

kk my paper was edited. Must have been one of my replacement questions.

There was one discriminant. -4 < k < 12 from memory

Yessir!

Tutoring allows one to use school as revision. Right now, studying for physics and chem is 1000x easier with most of the knowledge and understanding already in my head. Personally I think it is essential but thats just my opinion.

Proving h = 3(8-r)/4 and then finding value of r which gives max volume.

Was one but my school cut it out. school cut out probability as well. From what i see here, general consensus is that probability was the hardest question..hardest question for me was seeing the similar triangles in the water tank question.

Really worried tbh.

Pretty easy compared to other years. especially the last question. As for 3u, im fucked.

Lol cheers mate, i did 4u for half a year then dropped it. Half laziness (never touched a piece of hwk and staying back was a bitch) and half too difficult.

Youre year 11 whoa. Lol. good luck with the accelerating!

Please find the focus of (x+2)^2 = 4 - 8y Please show working, i dont understand! :(

Answer is A. cos(180-B) = -cosB

Was pretty easy, my school took out the hard questions. Reckon i got 99. (They chucked in a bs focus question and i forgot how to find it LOL)

a = 3 b = 5 c = -8

L = a + (K-1)d = a + Kd - d K = a + (L-1)d = a + Ld - d L - Kd = a - d K - Ld = a -d L - Kd = K - Ld Kd - Ld = L - k d(K - L) = L - K d = -1

Re: CSSA 2U Mathematics! Likewise. Good luck :) Who knows you may state rank ;)

State Rank = Highest HSC Mark = A combination of External Mark and Internal Assessment Marks.

Don't go to Truong but strongstereotype/10. Cabramatta is dope. Kebab shop gonna open now as well near the library so like..winning!
