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

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.

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....

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

for the coordinates and area of triangle

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

Area of triangle, 37.5 units2

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.

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?
