What did you guys get for the value of k? I got 1/5. Some of my other answers were 49root2/2 for the area, -1/6+1/2i for the value of z, root3i and -root3i for the two other solutions of the quartic equation, rotation of 67.8 degrees anticlockwise for the matrix transformation. For the first question, the sum was (n/2)(n+1)(n+2)(n-3)

Didn't find k, agreed with the rest, but i think i found 67.4 degrees anticlockwise (tan^-1 12/5)?
I dint find k either but my transformation was also 67.4 degrees anticlockwise. how did you show your root was correct to two d.p. in the numerical methods question

Didn't find that either, these were the only wrong things i got i think

Well my approximation was -1.64 so i tried doing f (-1.635) and f (-1.645) to see if there was a sign change, but that didnt work so 2 marks gone
Maybe you had to try again but using interval bisection or linear interpolation?
