b part 2 - are you sure there should be a n=0 term?

5.
a part 4 - you missed that question (i've got x < 2 as the answer)

Haha I completely missed that.

So you need y' = 3x<sup>2 – 12x + 9 < 0.

This happens at 1 < x < 3, doesnt it? It cant be x < 2. Take for example x = 0 (which is < 2). y' = 9 which is > 0.

Also for the series question, I figured that 0 terms would equate to a sum of 0, but I guess its probably more right to ignore the n = 0.</sup>

 

[Jago]

oh dammit, i misread. i found y" instead

bah the stupid mistakes will be the end of me. if i did the cssa paper i would've got 108-110/120 - should've been 118-119 if there were no stupid mistakes

5 b ii incorrect height

for 5bii you have the height as equalling 2 however the height == .5 therefore it should be 1/6 instead of 2/3- please clarify

ps, thanks for posting the answers

 

[Jago]

yes im also curious about that. i had 7.285u²

 

[acmilan]

Yup put height as 2 instead of 1/2. fixed now

 

[physician]

Yup put height as 2 instead of 1/2. fixed now

lol.. phewww....

well so far i've lost something like 6 marks.... 4 marks i stupidly did not attempt

and 2 ... simply stupid mistakes

[Xayma]

Yup put height as 2 instead of 1/2. fixed now

How did you beat me again?

 

[acmilan]

How did you beat me again?

2 or so hours to look over every single question

 

[Ghost1788]

Due to what
El Pueblo Unido said below

[goan_crazy]

Thanks for that Ghost1788, it was good team effort
Acmilan, can you put in a request to the admins to update the resources section to make it 2005 for new submissions
thanks

goan_crazy, please remove that link for a while. Our school has not done the CSSA 2005 Math 2U paper. The test paper might leak to fellow students if they are not remove. Our school will conducted the math 2u tomorrow August 15.

In the mean time, I ask you to please rmove that link. I believe that few students have know this paper and has the potential to spread to other students.
