So how do you think you went?

[sajib_mostofa]

At the beginning of the Q, it said the domain of f(x) was R+

[Whatlol]

what was question 4 a ?

[peachesxo]

it was way better than 09 thank god!!!
now for exam 2....
 

[Linkage1992]

Much harder than 09. But i reckon i aced it! 

[Stroodle]

Here's what I got:

Q1a) 3x^2 e^(2x) + 2x^3 e^(2x)

Q1b) 4/5

Q2a) 1/2 sin(2x+1) is an antiderivative

Q2b) p = 1/2

Q3a) g: R+ --> R, g(x) = x^4

Q3b) 2

Q4a) 4, 6pi

Q4b) -5pi/6, pi/6

Q5a) 1/2

Q5b) -2/3

Q6) a = 4/9, b = 8/9, c= 58/9

Q7a) 6/125

Q7b) integral (top limit 3, bottom limit 0) 6x/125 (5-x)dx

Q8) p = 1/2

Q9a) 2xln(x) + x

Q9b) 9/2 ln(3) - 2

Q10) a = 1/6, c = 1/2, d = -5/2

Q11a) h = 5 - 5/2 r

Q11b) S = 10pir - 3 pi r^2

Q11c) r = 5/3 (also must state nature of stationary point and why)

I got all the same answers, except for my stupid mistake on 3b

1 question: for the trig question did it ask for x value or general solution ?

Trig question asked for the values of between -pi and pi that would give the solution.

[samiira]

what was question 4 a ?

4a was askin for period and amplitude
period = 6pi  and amp = 4

for some reason i also got 5pi/6 how much marks would i lose?

(also must state nature of stationary point and why)

  i didn't do that...

[jammaj]

Hmm I got -1/125 for a in probaility. Bummer.

  i didn't do that...

did it even ask for that? ..

you will lose one mark

[darkphoenix]

Fkn last question screwed me up

I'm 100% sure it didn't. Would be retarded if VCAA penalise people for that...

[thushan]

It didn't, but I'm just trying to be as pedantic as I can.

VCAA may not penalise, but just in case...
