i thought paper 1 was horrible!
our teacher hadn't taught us the trig graph we were asked about!
i got 96% in my prelim though, so a pretty good appeal!
i got for the -11, that you cant find the square root of a negative no.
second one was ok though, but i got the surds one wrong!
i finshed the 2nd one at 2.45, but i stayed to the end to check over it about a billion times :L:L
im sure all of yous will have done fine!
ye i found the exam reasonable i guess, although anyway know what question 13 and 14 was on the calculator paper?? i thought it was really hard
q13 was pythagoras and 14 was trig equations
Can anyone post any answers that they know are correct for any of the questions please. Much appreciated thanks
If anyone knows any answers that are correct could they please post them thanks
I can hardly remember what i wrote in that paper lol, i just hope ive got a B!
Well the answers that I can remember are:
In one of the trig questions one side was 8 cm.
An area of what I think was a newspaper holder thing was 1300 cm squared.
48 degrees was an answer to the last question on paper 2.
Something along those lines, did anyone get the same as mine?
Yes, I had the same answers as you Lscott.
On the first paper, in no particular order, here are some of the answers:
For the sphere one I got 113.04.
a=45 (the cosine graph)
k=-9 (graph of y=-x^2)
coordinates of Q were (8,0) and b was -9, a=-5
the value fo the machine was roughly $150000
sectors were 150,200,10 (just multiply by 5, effectively)
the taxi fare was 11
the surd question simplified to 4sqrt(7)
in the sim. eqns, y=-2, x=7 iirc
height of the tunnel was like just over 3 or just over 4m, can't remember which
Aw yes, I remember getting some of those answers DerBoy. Nice to know I am getting a match of answers.
I took the paper away after the exam. These are the questions and the answers i got. I missed a couple out, and some might be wrong.
If i put this (2) it means to the power of. For e.g (3) would be to the power of 3.

8.) Maria has been asked to find the roots of the equation
x(2) + 3x + 5 = 0
a) calculate the value of b(2) - 4ac
Answer = -11
b) Now explain why Maria cannot find the roots
Answer = -11 is a negative number so it cannot be rooted
