I felt pretty confident in this exam, Question 11-14 was a breeze, only struggled with the 4 marker.
Stupidly got caught on the circle geometry in q16 and I have no idea why, the solution was simple as anything. Just a bit fried from previous questions I guess. This was my biggest downfall as it wasted my time to get onto the rest of q16.
I'm hoping for 80 raw, more likely 75.
Hey man. Thats great. Hope you can get yeh,

Dw my friends did the same. Did anyone else use alternate segment theorems and vertically opposite angles and angle in semicircle?
How do you think you went emilios?
Hm,.... emilios? Curious

Is this like the first time a 4u paper didn't have a probability/perms/combs question?
2007 had 1 question but it was balls easy (literally felt like it was from q12 of a 3U paper) but that's the closest it's been i'm pretty sure :p

Why is this not valid for the circle geo pt ii)

<APD = 90 (semi circle angle)
<BPC = 90 (semi circle angle)

therefore we have a case where vertically opposite angles are equal. Therefore A,P,C are collinear?

EDIT: Whoops I just assumed B,P and D were collinear. My bad.
yep i think this will be the downfall of most people in circle geo.
even if they went a really longwinded way around, they assumed it was collinear in their proof (i know a few people who did)

your performance today must be making 1st internally at your school more happy than you lol
well first internally at my school didn't sit the exam because he's been in hospital for a long time (didn't sit trial either), so i can't imagine him being too happy :/
second is probs pretty happy tho

easy. Dont worry you will be fine. And I dont think that you will get that anyways. Kostadalianas, stop scurrying around. How did you go?

He will get the highest mark at your school as his internal and external.

And btw whats the theorem called when a value for eg:
0^- < x < 0^+

and then you assume at lim n-> infinity x->0

pretty much
So what about using the velocity counterpart differentiation?
Btw I didnt use the method using sin and cos in the test cos I though it was shifty. Damn wrong decision.
