the last bit about the irrationality was only one mark tho!Originally posted by Mr.Moonlight
I think the Q8 of proving pi is irrational was done b4, i think it's not as impossible as Qs on probability. i thought last year's paper was extremely easy, and this year's one is alrite
and besides, about proving irrationality, it was done b4 with 'e' in 2001 4u. And that time there was significantly less 'leadup' questions.
