Nailed it,, tho dropped a couple of Accuracy marks,, i got summat like 9-23ln2 coz i forgot that the base of the triangle was 14-ln4, i just put ln4 in... oopsie. but apart from that i answered all questions (ran out of time on 8, nearly did it tho), which is a change from january where i answered, 2.

well it wasnt too shabby considering i only started revision from about 10.30 pm last night. i got most of it right ( i think and i hope), but what got me was the part in question 7 where it said find the area of R, aslo the identities in question 8 , i muffed that part up too. other than the mentioned probs, im thankful they they didnt make it bloody hard like they did last year

x^2 - 2x + 3 = (x - 1)^2 + 2

x = 1 gives lowere limit (2)
x = 4 gives higher limit (11)

U had to integrate under the curve between o an ln4, then find the area of the triangle between ln4 an 14. hopefully the answer is sumthin like 97-13ln2?? did anyone else get that???

damn i think i know what ive done,,,

x^2 - 2x + 3 = (x - 1)^2 + 2

x = 1 gives lower limit (5)?????

since when has - 2 x 1 = 1,,,, ?

ive put range as 5<x<11

x = 4 gives higher limit (11)

me = NONCE!
