would i lose a mark if for the sinA question, i wrote sqrt135 instead of simplfying it to 3sqrt15? also is the third quadrant shaded?? there are so many conflicting opinions about it, like the range but then wolfram alpha.. haha

I think it should be shaded. Why should the range matter? The inequality holds true for coordinates that are below the semicircle. If you were to graph , you wouldn't exclude the area under the x-axis because the range of the parabola is . Someone correct me if I'm wrong.

If I wrote answers outside of the booklet borders will they get marked or no? ._. I'm screwed if they're not ;.;

I'm pretty sure they don't get scanned... idk, I'd assume when they're scanning they'd double check, and if a marker only has half a solution they'll let someone know

Lol, i went through the answers then and i was running on about 93% up until question 15. It went down hill from there haha.

hey guys ! i think i gonna FAIL!

Guys for one of the question where it asked for find the coordinates for C, I just found the y value which was 10, but forgot to find the x and it was worth a mark. Is that a mark gone?
