The paper is definitely harder than last year! The last question is kind of hard ( for me ) and the circle geometry is a very tricky question.

Possibly one of the easiest test ever done. That binomial question was textbook material. Only thing I couldn't get was the last part of the last question.

Much easier than I expected given how hard the 2unit exam was.
Skipped a few questions, but feeling pretty good about it.

At least this exam progressively got harder unlike the 2U paper. But I do agree it was much harder than 2012... Fuck binomials.

I found it pretty good, just wish the 2U paper was in proportion to the difficulty of this.

Fairly easy paper ran out of time by heaps ffs. Wasted heaps of time on the rate of change question because I misread the question and it wouldn't work out for me.. Came home and did it easily

a) 3pi/10 (angle at circum is half angle at center property)

You used the wrong angle as the angle at the centre. The angle to use is the reflex angle which is 2pi- 3pi/5 =7pi/5.

Wasn't it a cyclic quad?

It's c
(2pi - 3pi/5)/2

Na a quad which had 3 vertexes on the circle one at the circle centre

its was 7pi/10 im pretty sure

a) 3pi/10 (angle at circum is half angle at center property)
The answer was C because the angle that was double the size was the reflex angle, not the obtuse angle, so it's actually (2pi - 3pi/5)/2 = 7pi/10, which was option C

Do your exam supervisors not let you take the paper or something?
