UNOFFICIAL MARKSCHEME Edexcel Maths Calculator paper 09/06/2016

Average grade boundary is 166, not taking into account June 2015

Knowing 1/2absinC= 18cm (squared)...
1/2 x 7 x 8 x sinC= 18
18/28= sinC
sin-1(18/28)= 40.00520088

Now use the cosine rule:

7²+8²-(2 x 7 x 8 x cos(40.00520088)) =27.20955764

Then square rooting it gives…
5.216278141

Then use the sine rule…

(Sin(40.00520088) / 5.216278141) x 8 = 0.9859246389

Sin-1(0.9859246389)= 80.4 (to 3 sig. Figures)

If anyone believes this method to be incorrect reply to this.

I'm one of the few people in agreement with this 3.7 method, and yes, you should get 4/5 marks for the working

And thus a debate between 3.7 and 3.8 began. Take your sides!

cam someone tell whats question 16 is, trying to remember if i got it.

pretty sure i got 98 but can someone remind what question 9 was asking xx

Were you here for the debate earlier?

it is almost entirely pointless taking November grade boundaries into account, most schools submit their most able students for early entry maths therefore the A/A* boundaries are almost always exceptionally high. If you just consider the June boundaries, the average is 161.

I did it, is there a mark scheme for it?

not that i know of

I got roughly 54 in this paper and about 55 or 57 in the other,what grade would this be overall
