For the temp of the milk question, what were the constants A and B?

To get locus of q: dy/dx = 1/t , then differentiate x and y values for q in terms of t, then use chain rule (dy/dx = dy/dt x dt/dx) and you get a value for t. Then sub in values for t into x and y, you get x= 3^1/2(a)/2 , y= a/2. Square both and add together and you get a^2

I identified that it was a gp but couldn't knock the answer out. Will this obtain a mark?

You had to use limiting sum towards the end (well I had to) and yeh I think you will get a mark

That was an absolute lovely paper!

Probability question holy shit SO good!!

 

[faisalabdul16]

For the last part of the probability you had to realise that there were 2 GP's.

Then you do limiting sum of both and add them together. You use the previous part and you get the answer they wanted

Response to the circle/parametrics question.. Just the first 10 seconds

 

[orcevalm]

the multiple choice took a while like can u not

A=23 and B=21 ??

i got Q4 wrong. LOL whatd you guys put

 

[iStudent]

I wonder what state rank cutoff will be. Hopefully not 70/70 cos I got 1 wrong :'(

 

[Kurosaki]

I'm so disappointed. Damn it BOSTES

wrekt

HAHAH same I put C

 

[iStudent]

I'm so disappointed. Damn it BOSTES

Probability q too easy for you?

 

[hi im trash]

wtf a projectile and 3D trig question???? So failed that :/ gg atar

what 3d trig o.0

 

[faisalabdul16]

I wonder what state rank cutoff will be. Hopefully not 70/70 cos I got 1 wrong :'(

It's always 70/70

I'm so disappointed. Damn it BOSTES

KUROSAKI how good was the probability man

 

[iStudent]

It's always 70/70

KUROSAKI how good was the probability man

Noooooo
Are you sure though? My tutor state ranked with 99 hsc mark :/

 

[panakap]

I feel like since there was no probability in 4u, BOSTES decided to put 7 marks of it in 3u hahaha

Overall, pretty straight forward paper. I had seen the last probability before but somehow didn't manage to pull it off. Probably a 1 or 2 /3 for that. Other than that smashed it

 

[GOsie]

Accidentally missed 4 marks of the exam - didn't see it. Was furious with myself.

Happened to be the parametric locus. After reading all your responses I don't feel so guilty.

omggggg i did all of that why did it not work out
