Quote from: "joechan521"
the slope field was a strange question.
i drew lines at all 25 points,
let the numbers be the gradient
2  2  2  2  2
1  1  1  1  1
.5 .5 .5 .5 .5
1  1  1  1  1
2  2  2  2  2
is this correct?


2.5 instead of 2

i got the exam paper in front of me.

pity that i dont have a scanner!!!LOL

i think i passed. hopefully 30+/40.

q.1 - did well. 4marks
q2a - good. 1 mark
b. - not sure but i showed some working out. i'll say 0 marks.
3. good. 3 marks.
4. good. 4 marks.
5a and b. good. 4 marks.
6.a, b, c good. 6 marks.
7a. attempted.got a weird answer. but forgot how to do Euler's method properly. ><. FUCKEN HELL! i feel so dumb. didnt have enough time also. so i'll say 0 marks.
b. solved it. i should get consequential marks. 2 marks.
8a. i drew a table with values. then should that it was gradients. messy though but readible. 1 mark.
b. solved it. i think i got it right. but i should get 2 marks minimum anyway.
c. sketching... easy. 1 mark
9. a. didnt show it was in terms of r. hence i lose 1 mark. got 2 marks probably.
b. solved it. 3 marks.

so i'll be expecting to get around 33/40. According to last year's paper, 32+ out of 40 is an A. so I hope that it was enough to get an A.

There was no room for a table. I just showed some little working out on the side.

I doubt it. I wrote -8/3 m/s^2 (opposite to motion).
