# Paper 12 maths

nvm i was wrong
what ans did u get for the area of the metal plate??

does anybody remember the binomial questions???
i forgot but i got a really weird answer!
root over

does anybody remember the binomial questions???
i forgot but i got a really weird answer!
root over
i got 5 as the answer

yeag
yeah do you remember the question? was the sum of the two terms was 90??????
i amm soo anoooyed how can I make soo many silliy mistakes????

what ans did u get for the area of the metal plate??
for that question..
part (i) yu had to use cosine rule=14.9
(ii) 45.9
(iii) 145.9

does any one remember the equation of the curve for question 1 nd the limits?

dnt know the equation but the answer was 12 pi for sure.what was the answer to trigonometry questions?

r my answers for the metal plate question correct?
r yu talking abt the one with identities ?
i solveed th first part but got stuck on the second nd i got 18.4 i think
wat was yurs?
nd wat was the rate of change?

area was actually 145.97 so rounds off to 146 (3 sf)
perimeter is correct...

rate of change was 0.105
and btw it was root 61 for the unit vector...

the limits were 2 and 3

i got 45 and 116.6 degrees for the trigonometry q
