yh i jst checked..they didDid they give any marks for method??
Yes the other one was right and I wrote the formula to get the angle...let's just hope for the best.. getting 3 is still better than losing 7im sure u calculated the other vector right so u get 1 mark coz it was easy the other one
i think for calculating angle we'll get method mark for stating the formula (without replacing values)
so 2-3 marks from 7 is not bad
Thank youu I hope they do the same this exam too :/ cuz losing 7 marks is alot for a silly mistakether is method mark... for dot product.. so u wont lose ur whole marks... method mark for quoting angle formula as well... RawanKhalid
yhh u are rght... i messed up qu 8 ... silly mistakes... jst hoping for method marks too..Thank youu I hope they do the same this exam too :/ cuz losing 7 marks is alot for a silly mistake
Yes it was trickier than last june and had new ideas I think it'll be like 61 or sthbtw paper was tricky a bit? n tougher than last year's paper or june's paper.. so wat are u xpecting as min grade for an A?
hope sooo.... fingers crossed!Yes it was trickier than last june and had new ideas I think it'll be like 61 or sth
June 14 was easier and its curve was from 61..and I think many people did silly mistake...I hope that helps get the curve lowerhope sooo.... fingers crossed!
same here! n nov 2013 it was 59 i thnk...June 14 was easier and its curve was from 61..and I think many people did silly mistake...I hope that helps get the curve lower
How did u get 34.1????i got 8pie and 34.1 for the angle hmm...how sure are u with ur answers?
How did u get 34.1????
yeah its 45.4 indeedI am 100% sure Angle MAC is 45.4! However some are saying its 34.1! If you got 34.1 plz explain how you got this answer
if i got 34.1 will i lose all 7 marks? eeeek!yeah its 45.4 indeed
coz its 3 marks for the part (i)
the 2nd vector was hell easy to calculate.
so its 2 marks for 1st vector to calculate. so there was a trick
we shld've found OX n then do the midpoint n hence calculate from A
but we were idiot enough to calculate it simply by assuming it 8i+4j+5k smethng like this...with ths vector u get 34.1 which i got too :/
but it ought to be 2,2,5 -___- then u get 45.4
