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

#### sadman

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

root over
i got 5 as the answer

#### sadman

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

yeh the answer was 5

#### cheesww

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

#### 123add1

i got 45 and 116.6 degrees for the trigonometry q

yeah same answers here

#### hateexamz

yup it wz 45 nd 116.6

thats correcct too

it was 10a^2-160=90

#### 123add1

yup it wz 45 nd 116.6
yes yes ! and does any1 remember the co ordinates of B? Q9.i got 2,2 and the shaded area as 28/3

#### 123add1

thats correcct too
i am really surprised to see that the gt of p1 is less than p3.relatively p1 is far much easier than p3 but many people including myself make silly mistakes!!!
