Easier than paper 1 imo.

Xgracie · 09-06-2014 11:05AM

That was a bit tougher than P1 but still pretty good! Hoping for a B

The only theorem I didn't learn came up aw I'm an absolute idiot -_- should have learnt them!
Rest of the paper was lovely though, if I'd known the theorem I'd say I'd have gotten nearly full marks

Much easoer than paper two.what answer did you get for the similar triangles.find a line eg |PQ| and anothe line. I got 13.5 for the first and 4.4 recurring for the second

I got fifteen for the first and 12 for the second

Some questions were a bit hard...harder than paper one and the mocks but otherwise fine

Liordi · 09-06-2014 11:24AM

I'm pretty sure I got 15 for the first and 12.6 for the second.

yaEHya · 09-06-2014 11:24AM

Did so **** in that

Ferrotype · 09-06-2014 11:25AM

I got that at first too but then I realised I had marked the wrong angles as being equal. I got 3.6 and 15 in the end

DanielChester · 09-06-2014 11:25AM

Wasn't that bad! What did everyone get for the final ratio??

What did people get for the volume in the second question was it like 70000?

Must have gone wrong ... I thought the ratio was 1:2.25

You had to add 9 onto the 3.6.

Oh I did that just forgot to write

Is it true you lose marks for writing in pencil?? Please not be true, aiming for the A.

I don't think so - it's just people are advised from writing in pencil as it fades over time.

Anyone know how to prove the rectangle was a rectangle and also was it divide by 100 or 10000 for the box question seeing as it was squared?

Same

PS. That theorem of the circle was such a surprise, good thing I learned it the day before, I had doubts it would come up after seeing it in a previous exam paper.

Divide by 100

I used congruent triangles, though, I'm sure there was other methods.
For the box question, I did the question in metres, but I think it's dividing by 10000 as 1m^2 = 10000cm^2.

Doesnt 70 euro seem a bit large for a cardboard box though? And also there is no way those thing were like 100 metres squared

coolerboy · 09-06-2014 11:32AM

What did you get for the second proofs question I got 64° and 32°

Thank god I thought I was the only one who thought of that

What did you get for the new height of the swing?
