i need some too :)

is this an assessment task? maybe u could try an hsc text.

i'm not too sure if the other ways work. the only downside with using my method is having to expand cos3x. it's 6 lines of working, so it's not too bad.

To integrate cos³x: You have to first expand cos3x. After expanding, cos3x = 4cos³x - 3cosx .'. 4cos³x = cos3x + 3cosx .'. cos³x = ¼(cos3x + 3cosx) and then you integrate from there.

are there any places where u can get trial papers other than the ones in the resource section? i've already got successone for 2u and ext 1.

:)

i think there are some combinations in which u can't get a UAI of more than 99 or so. but that would only occur if a student did all the low-scaling subjects. it's mainly the fact that the lower-scaled subjects are capped. so i don't think every subject combo can get 100.

wow, ur doing well :)

oh ok, ic.

check out the resources section of bos. * i'm also looking for additional papers to the ones in the resources section. i can't seem to find any nsbhs or nsghs trial papers...they'd be good practice if i could find them.

how would he have known what exam mark he got? bos doesn't release that info.

well, that proves exactly why 1st is the best position to be in.

oh, ic now.

worth repeating if u get 47/50 and then do ext 2? i'm not too sure if this is entirely accurate, but i think a couple of guys in my year got 48 or 49/50 and are repeating.....:confused:

true. waste of a few grand???

ok. one other thing....with a graph like tan^-1x + tan^-1(1/x), would u be marked down if u forgot to draw open circles on the y-axis at the end of each horizontal line?

i gotta compete with yr12 ext 1 and ext 2 guys as well. not only that, but they generally get near 100%, which makes it tough to beat them. my opportunity will come next year when i redo ext 1 (if my mark isn't high enough this year)

i can't be exactly sure that that is what the question is asking, but its only my own interpretation. is it an isolated question, or is part of a whole question? coz that might give u more of an idea of what they're asking.

i think a good tutor would motivate his/her student. that's probably the key to getting a good mark. unless u: a) don't understand the work/aren't grasping it as well as others or b) can't motivate urself to do extra work/study then i don't think u'd need a tutor, as they are the primary...

i've never used any methods other than the cross-method and the quadratic formula :) what other methods are there??
