actually, it is pretty much 1 of the only subjects with the MOST shortcuts. refer to the next conics quesiton asked that i just answered. we used a definition to get there in 1 line.

no man unless u can point a definition to me this could be done in relatively short steps, it could be a 2-3 mark question so it is worth it.

a. extremeties of the latus rectum so asec0 = ae (since by definition the latus rectum is the perpendicular line throught he focus) so sec0 = e as req'd b. again the top half and bottom half is symetrical so 2 x the top half and the top half is y coordinates of p so 2 x b...

this is a standard textbook question, make sure u can do this! b, find the coordinates of Q (i assume u know how to do that since u did a) then find its gradient find the gradient of SP and show that m1.m2 = -1 THUS IT IS PERPENDICULAR. c. well the line which goes through the...

i would prefer not going if we dont have to, my friends 18th is on the 4th. but like, if the place is close to sydney, maybe i can drive home sat arvo and come back or only stay for the 1 night

it comes down to what kind of UAI u want to achieve. ( you could get a high 99 uai with general maths, but if u combine that with standard english and other lower scaling subjects, basicly a uai of 100 becomes impossible because of the maximum mark restrictions) a 98 in general maths is...

anyone else going to the bootcamp from 3rd to 5th of march? how's the attendance rate? is this the compulsory camp they talk about?

dont be so sure i think it was 1992 hsc

basicly, the difference between first in the state and liek someone who gets low 90's is harder compex numbers and vectors. harder 3unit (the number theory) mechanics is ALL repeats, there is only like 5 questions ever for each chapter. Once u do some mechanics, u will fall asleep...

yea, i read it again and im like.... hmmm i hope he doesnt confuse that to be 216 or something.

ministry of sound was at home tongiht.. anyone go to that?

the first part is very easy what do you think about when it says right angle m1.m2 = -1 so basicly b^2/a^2cot@cot& = -1 so -b^2/a^2 = tan@tan& b. this ones a bit more difficault, since its not exactly 0,0 but if u get the gradient for P and Q and do the same thing as above you get...

. i think your really missing the point of sketching... always go back to your definitions. it could be an easy 4 mark Q in Q3 or so.. X^2 + 16y^2 = 25 is the same as X^2/25 + Y^216/25 = 1 and by your definitions... b^2 = a^2(1-e^2) as trev said in other post since a>b F...

im not sure why u r having a problem dont u know the formula's this is an ellipse correct so u use this formula: b^2 = a^2(1 - e^2) and the foci is S= (+-ae,0)

2 is simple just solve simultaniously (easiest way is to substitute in the ellipse x = -2y-5 then show that this creates a perfect square, 1 answer thus its a tangent. now that you know the y quadrant put it in the tangent and get the x quadrant.

call enrolment: 9385 1110 but isn't math1131 math 1A? so wouldn't you take math 1131 in session 1 and math 1231 in session 2? unless math1011 is the ext 1 hsc course that your doing first session, then math1131 in session 2 and math1231 in the summer session? but i don't know about...

i noticed that... one place is like req's for math 1A: *E4 in Math Ext 1 then another place: E3 in Math Ext 1 they just try to scare you to study i think.... most of the syllabous seems like the 4unit one. minus matricies *scared*

jesus man even actuarials only wants 180.... this is really scaring me. like i got 188 (so its over it) but... still, not by a comfortable margin.

how much? i bet i could get myself a late round offer.. apply for 9 courses with (V) next to them with uai's of 60 or less i have to get at least 1

i got 9/15 in the physics multiple choice! exam mark of 92 :burn: and i know of at least a 3 mark quesiton that i got wrong so that is 91 max markand 9 marks off from this and that = 82 slack!
