ic then im definately wrong.. anyways good luck to uz too! im getin around around 75/84 from past hsc papers under timelimit, once 100% and once 82/84. but i still make a lot of silly mistakes, usually 5 marks worth

u cant really try anythin to prove this coz u cant keep ur velocity constant.. just tell me in terms of physics.. am i right or the book.. i thought since the speed is constant, it is an intertial frame of reference, so droping an item will fall vertically? lol i think im wrong

check out the projectile motion question.. the last part doesnt quite make sense... it says that the plane is travelling at A CONSTANT velocity, then it drops this object and blah (read it urself) then the answer from the back of book assumes that the object has a initial horizontal velocity...

nope

lol? there're about 3000~3500 students doing HSC everyear, if 80% of them get e3+ why wud there be 1500 ppl getin e3-

i took Mathomat in.. i bought it on sunday lol.. i asked the examiner if i cud use it she said 'oh... i dont know, dont ask me' then she just walked away.. =) so i used it.. mine only has y=x^2 +sin n cos curve... no other formulea..

MAN I CANT BELIEVE THIS....... I MADE SO MANY MISTAKES!!! minimum 89/120

that was not 3d lol

THANK GOD i just drew 2 lines to the mid (top) of ellipse.. then use a^2+b^2=c^2 to find the half minor, then times it by 2! and same for the arg(z) at that pt, angle's a maximum, then minimum is negative that number

omfg whats majar n minor again?? i got 10 n 6 centre (5,3) r u supposed to write 5 n 3???????????? idid write 10(2x5) 6(2x3)

ok my max is 94/120 take away 10 marks of silly mistakes (i do those alot) --> 84/120 70%

Q8 (a) (i) got it (ii) got it (iii) got it (iv) didnt attempt (5 marks) (b) (i) this is what i wrote: use intergration by parts to find f"(x) then solve for f"(a)=0 & f"(b)=0 rearrange n make a &b subjects.. this book i have (phoenix?) says that if u dont have time to do the question, write...

Q7 (i)prbly made a mistake during calculation coz my ending didnt turn out to be right (ii) got that with a negative sign??? must be mistake during calculation too (2 marks) b. yep that was easy (5 marks) c(i).got 1 mark for proving n=1 (ii) lol yep got that out wasnt it -2? cant...

(i)81 (ii)0.0144 (iii)not attempted

edit: actually i got 2 aswell lol sides of square is 2 m remember so it can be biger than 1

1st 4 was good, cudnt do the circle geometric bit tho..only did (ii)

thanks

p( x)=3x^4-11x^3+14x^2-11x+3 solve p( x) over complex field + factorise P(x ) over real do this one plz!

cool thanks!
