How was the exam?
first few questions were decent but 4 and 5 💀
Q4 was so algebraic
Q5 was quite tough, brain was overloaded when i got to the last part.

Weird questions. Couldn't prove that a+b+2 thing for the life of me. The rest was alright but I thought some of the mark allocations were odd.

Yeah the diagonalisation question worth 4 marks is ridiculous

Yeah, I got the +2 part, and I managed to show k1 = -k2 but I couldn't find the value of k1. Supposedly you had to consider (a o a) and (a o e), but I still have no idea how to show k1=1

you had to do a o e and e o b

Exactly the same here. I tried to consider e o e = e but I was running out of time. My mate did it by just doing 0 o e = 0, 1 o e = 1 etc..

ahhhh now I see it thanks for that. Seems I misheard how to solve it when talking to others about the exam.
For the diaganolisation ( if I spelled it correctly) did you get 2 4 8?

For the recurrence relation solution I got
7*(4/5)^n + 3n^2+2n+2. Hahaha! Maybe not. I don't remember what I got but it looks similar.

Maybe 3n^2 +2n+1

Maybe 3n^2 +n+2

I agree with Hk, I got -n, not +n
I think it should be 2n+1 though. If I remember it correctly

What did you get for the actual solution?
