[2xL]

was the max radius 5&1/3

Yessir!

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

About the same as most papers imo, way to many similarity congruency stuff. And no locus, loan repayments, discriminent. Stupid superannuation instead which i had no idea about.

There was one discriminant. -4 < k < 12 from memory

Yessir!

Not in my one... Im positive it wasn't at least a direct discriminant qn. Was your paper changed a bit? Mine was untouched from CSSA

kk my paper was edited. Must have been one of my replacement questions.

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

Lost two of my three marks from that bloody question. I literally spent over half an hour on that question and didn't come close to proving it. Apparently you had to use tan :/

I used similar triangles.

probably was because discriminant is usually in it. I wish my school put it in instead of that probability or superannuation qn...

Similar triangles was the way to do it... i had no idea but that is what my friend did though.

Took me like 20 minutes to figure that one out too!!

btw did anyone else get like barely any a's in the multi choice?

 

[shajeeahkaleer]

GGGG

baby baby baby!!!

 

[Kostie100]

yeah i dont think i got any... maybe 1

 

[gr_111]

I used similar triangles.

Yep thats the easiest. Still took me a while to figure as well.

FFS i should have thought of that...

What did u get for the last 2 parts of the probabilty

 

[Demise]

For f sake, lost about 20 marks now... Hopefully I can still hit 70-75...

parts of the paper were really hard, parts were easy. I managed to get to 2(8-r) but I had no idea what to do after that.

and our paper was unedited and there was definitely a discriminant question in there. I remember cos I knew how to do it haha

where wtf??!!

 

[micwes12]

can't remember the exact question but I definitely remember it saying "use the discriminant to solve...." possibly I'm recalling from practice papers, but I'm almost certain it was in there. Maybe your paper was edited a bit?

I didn't see a discriminant question unless it was where you had to find a, b and c I think.
