    On the grid, draw the image of the unit square after it is transformed using the matrix
    3 0
    0 3

    How do you read of the numbers!

    Take each point of the square (normally 0,0 0,1 1,0 and 1,1) and multiply it by the transformation matrix

    For instance: Transform (1,0) using the matrix
    3 0
    0 3

    The point turnes into matrix
    x
    y

    i.e. (1,0) turns into
    1
    0

    3 0
    0 3
    x
    1
    0
    =
    3 + 0
    0 + 0
    =
    3 <---x
    0 <---y

    The point (1,0) is mapped onto the point (3,0) by the matrix
    3 0
    0 3.

    How did you all find it?? What did you put for 'x' on the circle question please? Also when you had to solve for 'x' (7 mark question), did anyone else get 'square root of 8'?

    For the 7 marker, the answer was positive square root of 8. Minus didn't work. You had to be specific. For Question 16, the Circle Theorem, it was 30 degrees. This was the answer to the circle theorem question with two triangles, on inside the circle

    what did everyone get for (x-a) is a factor of 2x^2 - 7ax + 3a, what is the largest possible value of a? i got 3 but was very very unsure, and for the last question did your proof effectively end up at both fractions are equal to 1

    yes i got both of those. I also put 3, but wasnt sure. Sin30 and Sin150 are both half so they went over to 1

    I got 3 but I'm not sure how accurate my methods were...
    Hopefully we all did well as we think we did!
    Praying for an A*^ but an A* wouldn't be the end
