I had 4 exams in one day the week before aha.

Anyway it was okay, messed up question 9 last question (3+1 mark) about

and last question,

question 12, stupid intergration (finding area) of the stupid sin graph.

But other than that aced the rest so i figured the highest icould get is around 68/80 but realistically :P, 65/80, dont even think thats a* thou.

sorry to spoil anyone's mood :P
but i think i got everything but 1 mark -.-

Title: Re: Additional Math .... Killer :-[
Post by: Anonymous on June 04, 2009, 05:06:51 pm
I lost, I believe, 2 marks on the velocity q and 1 mark for forgetting to include the pi in 6pi for the period :X

do u guys know wen the grade boundaries come out ??
Title: Re: Additional Math .... Killer :-[
Post by: vanibharutham on June 04, 2009, 05:14:22 pm
dont know when the grade boundaries come out...

Did you guys do EITHER or OR?

I did OR... it was broken into more reasonable steps that EITHER
Title: Re: Additional Math .... Killer :-[
Post by: Anonymous on June 04, 2009, 05:15:38 pm
I did either - 'twas pretty straightforward :)
Title: Re: Additional Math .... Killer :-[
Post by: vanibharutham on June 04, 2009, 05:24:04 pm
anyone remember their answers?

i can vaguely remember some...?

question one i think was 0.8 radians and 90cm2
Title: Re: Additional Math .... Killer :-[
Post by: Anonymous on June 04, 2009, 05:26:00 pm
Yeah, I got that ^^ I remember for the q on polynomials, I got x= 3, -4 and something else :p I'm not sure about the -4 but I'm pretty sure the first factor was 3 :D
Title: Re: Additional Math .... Killer :-[
Post by: vanibharutham on June 04, 2009, 05:27:23 pm
3, - 5 and 0.5 :P

I have a question: for the log graph which you had to draw, you don't have to construct a table, do you? I just plotted my points.
Title: Re: Additional Math .... Killer :-[
Post by: vanibharutham on June 04, 2009, 05:30:20 pm
umm the straight line graph conversion..

i came out the exam with a big smile :D:D because i thought it was really easy

and apparently NOONE in my grade got the damn graph....

i cant remember exaxctly

9010 and -1.2  were my values??
Title: Re: Additional Math .... Killer :-[
Post by: Anonymous on June 04, 2009, 05:32:25 pm
Mine was a bit off, but I got the method right :) I mean, they told me to use my graph, so I did. So, do you have to show your table of values or is having plotted your points correctly enough?

NICE.

I got -1.2 too :), i rounded it up from -1.98

Loads from my year got it wrong and some didnt even do it. But that question i found easy. Damn maybe i should have done the OR kinematics question. Anyway wish me luck tmmr :) Gonna sleep soon

I thought the paper was AWESOME!!!! I hope tomorrow is as god. for the graph question i got lgk = 3.95, therefore, k = 8912.5 and n = -1.2  and s = 79.4 from my graph. i did either. so the amplitude was 1 and the period 6 pi. the x coordinates were pi/2 and 5pi / 2 and the area something like 2.05 - 2.07 sq units. guys post more of ur answers and best of luck for tomorrow
Title: Re: Additional Math .... Killer :-[
Post by: vanibharutham on June 04, 2009, 05:41:26 pm
for the coordinates and area of triangle

C ( 4,6 )
Q (8.5,0 )

Area of triangle, 37.5 units2
Title: Re: Additional Math .... Killer :-[
Post by: Anonymous on June 04, 2009, 05:43:39 pm
Yeah, that question was unbelievable; 7 marks for that?! xD

Lol awesome i got that.

Wow i didnt too bad i guess haha.

Oh and the EITHER question was easy, especially the first 2 questions , 1 amplitude , 6 pi , x coordinates easy 4 marks 1.57 and 7.8 something in radians.

But oh gosh, i think i kinda ran outta time (onlyy have 5 mins to do last question) so panicked, i hope i get some method marks thou as i tihnk i intergrated sin correctly.
Title: Re: Additional Math .... Killer :-[
Post by: vanibharutham on June 04, 2009, 05:51:03 pm
i did OR...

if anyone else did OR...

i remember i 3/8 for the very last answer

and that k = 3

Please can someone tell me what they got for the velocity question (final part where you have to give the time)?
I got 13:30.
And for the log graph, did you just have to read the values of the graph or work it out? My line wasn't perfectly straight. Is that OK?
What did everyone else get?
Which questions did you find hardest?
What is your estimated score?
Title: Re: Additional Math .... Killer :-[
Post by: vanibharutham on June 04, 2009, 06:32:06 pm
i got 13:30 :D

and umm 31i + 43j or something??
Title: Re: Additional Math .... Killer :-[
Post by: lil^$tar on June 04, 2009, 07:24:51 pm
what do you guys think will cam 2moro...i pray no graph and relative velocity cams

Post by: Sweet_03 on June 04, 2009, 07:25:55 pm
I don't remember any of my answers ><
but Q11 .. i solved it .. but im sure its not right !

guyz temme is it ok if u sketch da graph on da answer sheet???  im tensed because sum of my frnds did it on a graph paper....
Title: Re: Additional Math .... Killer :-[
Post by: Anonymous on June 05, 2009, 03:13:10 pm
I think you were supposed to use graph paper as it was one of the requirements on the front of the paper.
Title: Re: Additional Math .... Killer :-[
Post by: AN10 on June 05, 2009, 03:22:25 pm
Oh sh**!... will they give me any mark if the graph otherwise is all correct :'(
Title: Re: Additional Math .... Killer :-[
Post by: Sweet_03 on June 05, 2009, 03:22:39 pm
I did it On the answer Sheet Cuz its a sketch ! :-\

I don't think it will matter ! Cuz You will not need a scale ? right ?
Title: Re: Additional Math .... Killer :-[
Post by: Anonymous on June 05, 2009, 03:25:38 pm
Well, why would they specify that 1 sheet of graph paper is need if you didn't have to use it? Regardless, so long as you got your critical values correct, I don't think there should be a problem with that.
Title: Re: Additional Math .... Killer :-[
Post by: vanibharutham on June 05, 2009, 03:30:49 pm
i did it on an answer sheet as well, my tteacher sed its a sketch, unlike paper 1 wher u had to graph properly

Ah well

hope cambridge are leniet

i didnt use graph paper neither did anyone in my class .... it said sketch so i gave them a sketch .. if they mark me down for that then i will get pissed !!
