Thats a load of exaggeration. Maximum posible is about 7 or 8 pages in 40 minutes lol..but they may be talking about the BOS paper, in that case its easy to write 15 pages in 40 minutes if u have large handwriting cause the paper's lines are very wide. Some tips to write fast - write cursive...

hey lol that method works just got to simplify what they've given you (2n+1 - 2) - (2n - 2) = 2n+1 - 2 - 2n + 2 = 2n(2-1) = 2n RHS = 2n+1 - 2n = 2n(2 - 1) = 2n = LHS as required

You can prove it by induction, but thats 3 unit. But I guess it might still be valid. I will skip to the assume true for n=k step: 2k+1 - 2k = 2k+1 -2 Need to prove true for n = k+1 i.e. prove: 2k+1 - 2 + 2k+2 - 2k+1 = 2k+2 - 2 LHS = 2k+1(1+2-1) -2 = 2k+1(2) -2 = 2k+2 - 2 = RHS...

If you get in early I don't think theres a time limit. Our principal said that he talked to a student every day for 3 hours leading up to the HSC

lol, i was gonna call up and see if they had any modern teachers who knew anything about the UN. Sorta didnt get around to doing it though, but would have been quite funny - seriosuyl, theres not a single book available on this topic, and its in the sylabus as an option for MH lol :p

Call in early, like as soon as it opens - not 2 days before your exam lol, I heard thats when it will be packed. When it gets really busy apparently they limit you to 5 minutes per call as well

lol Im just learnign about traiditional and political interpretations, I will be screwed if they ask for a feminist interpretation

The Cambridge 2 unit book has really good exercises and nice worked examples, otherwise, try the resources section of this site

Yeah..but its good to know v = 2pir/T because thats where Kepler's Law is derived from

haha same, Engilsh is easily the worst followed by IPT (for me anyway)

For the second one its clear from the graph that the spacecraft would want to send signals that can have the best possibility of travelling through the atmosphere and down to the ground where the signals can be picked up by a large satellite dish. What you need to do is convert the MHz to...

2 unit maths. Cant wait

11. just use E = hf = hc/l where l is wavelength so E = (6.626 x 10-34)(3x108) / (20 x 10-9)

Always write down the possible products then choose the most positive value (thats the one that will occur), at least in standard conditions (1 M solutions, standard temperature etc. )

nah, hes just finalfantasy, bos's online integrator (among other things) hes graduating this year

Yeah, like Dreamerish Im just doing as many past papers as possible. Hopefulyl I can finish that success one book, and then some

thats rubbish, u can make it up, the markers dont possibly know ALL practising scientists in australia lol

haha yeah..i was very lucky our teacher told us the good way :D

The way I learnt it, it can be applied to everything h = (b-a)/n where n is one less than the number of function values (i.e. n is the number of intervals/strips) A = h/3 [f(a) + 4f(a + h) + 2f(a + 2h) + 4f(a + 3h) +...+f(b) ] Its basically the same as the other formulas mentioned above.

And for 10 b: (i) It is known that the speed, v, is inversely proportional to the depth of the snow. i.e. v = A/h where A is constant. this also means that dx/dt = v = A/h Since the depth of the snow, h, increases at a constant rate, let the depth h be represented by mt, where m is...
