OCR MEI C3 - Tommorow

Ugh! I've just realised that I did the populations question wrong. I didn't realise that P was in millions, so I wrote 8000000 = 5 + ae or whatever it was...

Oh well, at least I'll get all of the method marks for it.

That's right and it's what I got.

8000000 is 8 million.

"Where P is population in millions".

I reckon we'll get 3 out of the 5 marks, or something like that.

Ohhhhhhhhh well.

Maybe 80% of the people who've done this exam may have made that simple mistake and examiners may then excuse this ...

And anyway, nothings wrong with the maths, unless english teachers are marking our maths exam papers - we won't lose that many marks.

For the coordinates (Q6)...

I think...
A and C were equivalent points (as they were f(X) and f-1(X) )... so A(pi/2, 3) and C(3, pi/2) (or switched round???)

B i founda bit more difficult to get in the end i got B(1, 0) which i'm almost certain is wrong(??)

Anyone else have an idea?......
