    9a) Find the transformation represented by Matrix \begin{pmatrix} \frac{1}{\sqrt 2} & -\frac{1}{\sqrt 2}  \\\frac{1}{\sqrt 2} & \frac{1}{\sqrt 2}  \end{pmatrix}.

    Answer: Anticlockwise rotation through 45 degrees about (0,0)

    b) \begin{pmatrix} \frac{1}{\sqrt 2} & -\frac{1}{\sqrt 2}  \\\frac{1}{\sqrt 2} & \frac{1}{\sqrt 2}  \end{pmatrix}\begin{pmatrix}  p  \\\ q\end{pmatrix} = \begin{pmatrix}  3\sqrt 2  \\\ 4\sqrt 2  \end{pmatrix}

    Therefore, p - q = 6 and p+q=8
    Which gives p=7, q=1.

    c) Distance between (7,1) and the origin = \sqrt 50 = 5\sqrt2

    d) Initial Matrix squared. Answer \begin{pmatrix} 0 & -1  \\1 & 0  \end{pmatrix}

    e) Transform (3\sqrt2, 4\sqrt2) using matrix squared.

    Answer = \begin{pmatrix} 0 & -1  \\1 & 0  \end{pmatrix}\begin{pmatrix}  3\sqrt 2  \\\ 4\sqrt 2  \end{pmatrix} = (-4\sqrt2, 3\sqrt2)

    I hope I haven't made any stupid errors here. Had to do it from memory since the paper's been taken down.

    You are fab.

    All the content is C1-4, but its a three hour paper where the questions are really weird.
