Do you mean a = 3 so the determinant = 0? Get 1 mark if you said that.
Thanks, also another question: For Question 8 iii.) if I stated the wrong evaluation of sum to infinity, and thus did not add a sixth to the answer, however stated the correct summation at the start (Sum of n to infinity = Sum of 1 to infinity - Sum of 1 to n-1). The only thing I missed was the sixth, so how many marks would I lose for this?

1. (5 marks)

2. (i) (2 marks)

(ii) (5 marks)

3. (i) and (1 mark)

(ii) (5 marks)

4. (i) (2 marks)

(ii) (2 marks)

(iii) (2 marks)

5. Proof (4 marks)

6. (i) (4 marks)

(ii) Sketch (2 marks)

(iii) and (3 marks)

7. (i) Shear with x axis invariant taking the point (0, 1) to (3, 1) (2 marks)

(ii)

Reflection in the line (6 marks)

8. (i) Show (1 mark)

(ii) (6 marks)

(iii) (3 marks)

9. (i) Show (3 marks)

(ii) Determinant = 0 when a = 3 so no unique solution. The equations are consistent because 3 x equation 3 - equation 1 = equation 2. (3 marks)

10. (i) and (6 marks)

(ii) Show (1 mark)

(iii) (4 marks)
Just wondering how many marks I would lose in 2 ii) as I didn't see the conjugate parts so I used the part I got in part i) but I did everything else on that question right only used the non conjugate z how many marks would I lose?

Probably just 1.

Thank you
6. What was the last question?
7. I know this post was a while ago, but I've been doing this paper as practice for next weeks exam. I was wondering how to get the answer to 7)ii) I've tried a lot of things but I'm still not sure! Thanks
