well it looks like i've caved in under all this peer pressure ;) couple of questions Ho: that the effects are additive, is this the same as when we test for interaction? and then if our F obs > F and we reject it, does this mean the effects are not additive, ie there's no intereaction...

just wondering if the rumours are true are the final exams are direct copies of each other with different numbers i skimmed through part B of the 2003 paper and 99 paper, and apart from different progams used for output they appear the same and i noticed in the MC that Qs 16-40 all relate to...

hahaha and what's that supposed to mean? and i guess it looks like i'm going take a gamble and not bother with the 2-way anova :o

oh i know i'll be able to put it in, sideways if needed ;) but we didn't even cover it in tutorials did any other classes manage to do it?

what are your takes on the 2-way anova? did Ma hint that the anova question was gonna be 1 way or 2? because i'm consideirng not even studying it, seems like too big a time-waster to be in the exam

how are you guys finding the tutes? is that the best thing we can base the exam on, cause so far i've only been looking at the examples in the notes

ooh ooh i know this one ;) differentiate twice to get to acc .. x = -12 sin(2t + 5) and now looking only at the sin(2t+5) part, this can only have a max value of 1 (it range of values of from -1 to 1) so max acc is 12

thanks alot acmilan! you misread the question with part b and missed the c in biii but i got the idea ;) anyone got c?

hahaha it seems im the one who's up too early and still sleepy

attached image ;)

hi guys all help appreciated thanks

hi guys, i got some general questions question 3 - MGFs and the CLT. i remember him saying there were no normal tables provided, so what type fo CLT can he ask, and do we also have to know the characteristic functions, the probability functions and any of the other ones? another question...

no worries i got it thanks for all the help shafqat and FF :)

guys i tried it and my two equations are asin@ = -2 and acos@ = -10/root3 the answer doesn't come out from there

yep i got it thanks shafqat - was making stupid mistake as usual ;) what about the second one?

shafqat ive done that and i get the equation x^4 - 8x^2 + 4 = 0 and that doesn't result in x = plus minus 10-^0.5

acceleration = 8x - 2x^3 when x = 2 v = 6 show the particle moves between plus and minus root 10 quesiton 2: a particle in SMH has acceleration = -9x EDIT: x = asin(3t + alpha) initially the particles accceleration is 18ms-1 (possibly a typo, and may mean velocity is 18) and at t=...

anyone know about this?

ok guys specific question: week 8, lecture problem 2....are we supposed to know how to do that?!

hasn't anyone else got some info about the final exam? what sort of stuff should we be concentrating more on...equations like all that correlation and covariance crap, or definitions/
