I did the EXACT same. We were supposed to use .5bh, but we'll probably get a mark or two for working out the correct magnitudes of the required sides.
Didn't it ask you to use the smaller angle? Or have I misread?

For the stationary point question did they ask for exact values?
Yeah, extremely fiddly since you had to use s^2+c^2=1 to find sin(t) first and then substitute back in.

Then what was the problem with using c as ~12.7 or whatever it was?

It's because C is opposite of the resultant vector however 12.7 was opposite to one of those vectors.

.........****, so I should've used 90-alpha instead

The two vectors were perpendicular so C would have been 90.
9. Any one has the paper??? Can you upload the pics please??? Thank you!!

I believe I have realised the problem, I drew my triangle wrong, have AB perp to OA instead of OB so my angles got mixed around

11. How many marks will I lose for substituting the bottom as u instead of root u for question 6?

12. So annoyed at myself, used vector multiplication from FP3 for the area question and managed to get it wrong. Then messed up the easy parts of the parametric question and the last question was just???
13. Anyone else search the back of their paper, thinking they missed the DE question?

16. I think I got 66-68 marks.

What do you think 66 will be in UMS? x
17. Anyone got workings for question 6? For some reason still can't work it through :/
18. I ran out of time on the last part of the last question. Do you think I'll get a mark for separating the variables? So annoyed cos I could've done it easily if my time management wasn't so poor!

Mid to high 90s?

Would 70/72 be full ums
You obviously know that's full UMS.
