2012 CSSA Maths 2U (4 Viewers)

[2xL]

Was pretty easy, my school took out the hard questions. Reckon i got 99. (They chucked in a bs focus question and i forgot how to find it LOL)

 

[2xL]

I think i said A because i thought sin(180-B) = -cos(B) and so used the sine rule with a + instead of a - to account for my negative angle. but hey, could be completely wrong

...thinking about it now, my reasoning seems completely wrong. oh well, one less mark

Answer is A. cos(180-B) = -cosB

Was the first part of the probability qn just 4/7. Seems too easy...

bump anyone?

 

[Kimyia]

Answer is A. cos(180-B) = -cosB

ahaha i dont know why i wrote sin, but yay I think I put A!!

 

[Roy216]

bump anyone?

I put that too, im pretty sure thats the answer

 

[MATHmaster]

Answer is A. cos(180-B) = -cosB

Damn! There goes one mark... along with others!

Youre year 11 whoa. Lol. good luck with the accelerating!

Thanks! But I have to admit, you're a beast for someone who only does Ext 1 Maths!

 

[Johnstan]

anybody have the exam?
i want to see how hard/easy it is relative to last years one.


also, for those doing 3unit... u ready?

Not the hardest exam I've seen compared to some others, still u can't go in without proper study

Lol cheers mate, i did 4u for half a year then dropped it. Half laziness (never touched a piece of hwk and staying back was a bitch) and half too difficult.

haha what was hardest question in the exam?
any loan repayments ?

Was one but my school cut it out. school cut out probability as well. From what i see here, general consensus is that probability was the hardest question..hardest question for me was seeing the similar triangles in the water tank question.

what was it lol?

 

[MATHmaster]

BTW what was the answer to the annuities question? Anyone?

 

[2xL]

what was it lol?

Proving h = 3(8-r)/4 and then finding value of r which gives max volume.

 

[Johnstan]

i heard this years paper was very calculus based?
alot of volumes/integration/area etc...

 

[Kostie100]

Proving h = 3(8-r)/4 and then finding value of r which gives max volume.

was the max radius 5&1/3
