    It was y = sin x + 1

    And y = 2 sin x

    The explain question was for y = 3 sin 2 x

    The answer was:

    The graph has been stretch parallel to the y axis by a factor of 3 and then stretched parallel to the x axis by a factor of 1/2.
    dam, i only got the sinx+1 part...ah well...hey, was the angles question 80 degrees?

    phew, 80 degrees didnt seem rite esp. cos there were 4 marks available. the vectors proof was hard.....i dun sumthin like PO + OM = PM but i knw it was wrong cos again, i got lost

    i dont think i dot lost in the proofs, its just that i did a load of waffle. my teacher said if you get stuck then pair up anything and everything and a reason will eventually click.my reasons were so patheitc. did you get (AAS) as the final reason for the congruence one?

    I got SAS, I figured that

    The Line through the middle was common - S

    The two 10 degree angles from the tangent were common - A

    And the two sides that went up to form the triangle were equal - S

    How did you get the AAS?

    Thanks

    I also got 83% for that surd rectangle question. Although the answer was 83.333 I'm sure at least 4 out of 5 marks will be credited for just 83%?
