i caouldn't get the one with the triangle, with the sides x, x+1 and 2...i know i should've been able to do it, anyone care to enlighten me?

is my answer right

I was pretty much stuffed from the start of them exam. I completely forgot how to differentiate exponentials.

 

[howareya]

you just look at the standard intergrals and do the reverse

 

[Jinglebell]

uh...i can't actually remmeber what i got, although i don't thaink it was the same as yours...but then, i probably made a mistake in my rushing anyway, so don't trust my judgement

 

[howareya]

did you work it our like i did

 

[Jinglebell]

i think i actually did it differently, but your working looks valid to me...i think i may have had sin x = cos x, without the negative...geez, i always manage to leave out a negative somewhere!

I tried to do that but I could not get my head around it.

 

[howareya]

what about the train?

 

[SoCal]

I cannot even remember the trail question.

 

[howareya]

read the first page...it will refreseh your memory

Howareya, sorry but our school took out the Practical Applications Of Calculus In The Real World because some classes have not done it.

god that was the worst 2u exam i've ever had. That was bullshit, i mean comn !? wtf was that. Section 9 and 10 where so impossible, what where these guys thinking.

God, how bad do they want to give it to us students.

I'll be lucky if i even get 70 % for that exam, even though im like ranked top 5 in my school for 2u, that exam was shocking. and yes i did study

what did people get for the volume for y = root cotx

i got 8

cotx = 1/tan x
tan.x = sinx/cosx

therefore: cotx = cosx/sinx
cosx=d/dx sinx
hence this equals to ln sin.x

i think thats how u do it

hye yeh i think i did ok.. i just lost my first place in 2 U though so im cut.. oh well 3U tomoz!! yay!!!!!!!!!!! yeh i thought the test was ok... i got through it pretty easy except for #10 the end..

im so glad all of you people are saying "that was nothing like previous cssa" - on weekend i did 4 cssa previous year's papers and iw as cheering! i started relaxing and watching tv

can anyone actually give an explanation as to WHY this year was SO HARD compared to previous CSSA? it doesnt make any sense to me? all of a sudden they just release 2003 paper with really hard (in comparison) questions

that was totally f*ked

 

[Chand]

umm...apparently the hsc changes from hard to easy, from one year to the nextconfused: ), from what i've heard...mayb it was trying to do that and prepare for the hsc...

 

[howareya]

THE TRAIN QND what did people get

 

[Winston]

fuck it was shit


question 9 and 10

and i honestl didnt know u can integrate a log!
wtf?!


and i couldnt get the height of the rectangle to minus it out

bah its fucked

 

[howareya]

dont worry
