1. lol resolution not great there, try again

(I guess they will technically be parts of circles due to the sign concerns)

Forgot the holes but I think I put notes adjacent to each graph stating where the discontinuities were

My favourite was q7, if I did it correctly at least, if not q8 or q1 were nice too imo

6. did anyone get to the point where they had 301^2 - 900 in question 1 and had to find two factors?

ah i got as far f(x)= and didn't really know what to do next so just left it like that. Thats probably why I didn't have a clue what to put when they asked you to state what k meant at the end.

It's the difference of two squares.

For question 10, was lambda = 2+root5, e = root5 - 2? I wasn't entirely confident on this one
Just redid Q10, got 2+root5 again for lambda, perhaps 3 of my friends all got the same but wrong answer, maybe there is a popular mistake but I can't spot one!

10. Anyone do question 12 and just get the answer 1/2 for everything?

I didn't really like Q1, it was quite dull and the bulk of it was just expanding things (unless there is a trick I missed?) Whereas the end result in Q8 was very nice imo

oh for **** ******** ****** ************ sake
14. Q13 is the one that I am slightly dubious about, I worked backwards from the answer for the second part, did anyone get a full on this? If so what was the answer to 'Write down the probability that the second email is delivered after time t'

What did your friends actually get cos I was quite happy when i got e to be a value 0<e<1/3 i mean i thought that was quite a small margin?

Nah I did it the same way too, it was just a nice relaxing way to start the paper

Think they got 2+root3 for lambda, but I can't remember really. I just assumed I was wrong because 3 of them had got the same answer.

It was my last question actually, I attempted it first and ended up not being able to expand (1+X)^4 came back to it at the end and got it though.

20. would quite like one of them fancy polls to gauge how hard the paper was compared to previous years.
