    what did you guys write for "why is T self-inverse" for the matrix question?


    Posted from TSR Mobile
    I had no clue, I just found the determinant of the matrix.

    What was the geometrical relationship between those lines?

    I put they were parallel, what was the other mark for?

    Also was z^2 -8i ?

    And for the modulus did people get 2.34?

    You had to find the inverse of T. It was the same as T. So it is a self inverse

    No idea for the lines. I got a=-1 and so the modulus was sqrt(5), which is 2.34.

    If you found the inverse of T you would show it was equal to T.

    1. rotated 135° or 3pi/4

    2. Dunno, didn't get there in time

    3. yeah

    Yeah I got -1 for the determinant.

    Think i got ~50 which sucks... most questions were easy. Got confused/ stuck on the chord question (tried and failed), both inductions lol (obvs managed for n=1 but failed in n=k+1 ) and on the find a when z is a real number.. disappointed not sure how i could have done better. Thought series was my weak spot but that question was simple

    One had length sqr(5) and other had 2sqrt(5). So it is twice the length. I guess the first mark was working out the length

    Why do you delight in telling people that? I've got 75/75 in past papers before and done a past paper every week since January and I found it slightly more challenging.
    Stop trying to antagonise.
    Nah jokes I know her the paper was ****ing solid probably dropped about 20 marks

    For the modulus, I got 5? Thought it's just a real number with no 'I' component...

    Enlargement scale factor 2 followed by a translation of something like (-4,-3) dont remember the exact number
