this reminds me of exactly how i felt after my first math assessment. i let it 'dishearten' me through the entire 1.5 months of holidays which made me feel even more crap about myself to an extent where i was so stressed out i couldnt study for math in the half yearlies. when the trials came i...

im pretty sure they do have people on equal rankings. the school has to send in whole numbers to the board (as to what my teachers told me) and seeing as most the courses in my school have >100 students, it would be impossible to give everyone different rankings as ur ranking is dependant on how...

oh, phew. so i still didnt have a chance. Congrats by the way :)

just out of curiosity, what was your UMAT? because although i applied for it thorough UAC i stupidly forgot about lodging the application directly to the uni and i want to know if i had a chance

a) ---> the hydrocarbon chain is not polar but is instead held together by dispersion forces between the C and H atoms. c)---> carbon is not an electronegative atom d)--->all carbon atoms are the same length.

i was thinking about combining with arts too...and majoring in Latin @ unsw (but then they decided to get rid of the course) but eitherway, if you do do that, dont you still have to study other arts subjects whilst studying your major?

Just wondering, how much does the title of a creative count towards the actual mark? im currently writing one and the title isn't as great as that of many others i've seen so im not sure whether i should waste time trying to conjure up something better :/

just remember that the electron is not emitted from the electron cloud but instead from the nucleus of the atom (like alpha decay) that way u'll have to remember the formula which shows how an electron is formed, as there are no electrons present in the nucleus of the atom

i see now thought sums and differences was only an ext topic? thanks

i kinda revised my yr11 content yet i stil cant figure these out and im spending far too much time on it than i would like. Please help :) the q is: expand and simplify sin(pi/6 -y) i cant go further than; sin30* - siny ..and if someone could also mention what part of the prelim course im...

lol, my bad, didnt read it properly confusing is correct, i never knew that was a possibility

You wouldn't need the umat, thats only for undergraduate; afterall UMAT=Undergraduate Medicine and Health Sciences Admission Test :)

the question is : simplify (n-1)^C k-1 <--subscript + (n-1)^C k <---subscript (sorry for how weird it looks, i dont know how to do the subscript/superscripts thing on here) i don't know how to solve it, so can someone please explain/show how?

dw, even if you understood very little this yr, it will all seem heaps easier when you revisit it nxt yr

Thanks heaps :) as you said, a silly mistake. i made (3, -1) as the centre instead of the other way around...and i was wondering why (-1, -2) wasnt directly below C as i had previously calculated XD just wondering, would it also be valid if i said angle ZXY= 90° because it is the angle in a...

i was looking over my prelim textbook and i discovered that i never did this question. After trying to solve it for half an hour, i thought i would just post it here. the question is: A circle has centre C (-1, 3) and radius 5 units. a) find the equation of the circle b) the line 3x-y+1=0...

+2 i just hate the title: "Exams are in the pink" and the way the whole article positions the reader to think that feminists are responsible

for validity you can also have a control (or two) by placing a test tube of each alkane and alkene (without the bromine water) in the same environment as the hydrocarbon+bromine water test tubes, showing that the colour change with the alkene is purely a result of the addition of bromine and not...

lol, yep, so hopefully its right :/

its in the water topic. capillarity is the tendency of a liquid to rise up or fall down tubes right? well the up and down movement is a result of the unbalanced forces (suface tension) of the liquid. and water has surface tension due to its hydrogen bonding :) someone correct me if im wrong please
