Willa, two words to your problem: Leibniz's rule.

unfortunately it is not that simple because the limits contain "a" in them

-sin a^3 / a + 2 sin a^3 / a^2

how on earth did you apply liebnitz to get that?

dude. look up leibniz on mathworld

is that your answer?

patch: Ansorge didn't give Leibniz Integral Rule in his notes. But there is a question which requires it in the example sheet: G1.

Anyone know how to solve vector equations?

axr + kr = c

and r is?

no i dont think it is the correct answer, thats why I'm confused at your application of leibnitz. RichE is probably right!

Well... that's what I got for using leibniz. I'm going to avoid things like that tomorrow.

Btw - Chloe may that be a lesson to you. :wink:

Don't get drunk on an empty stomach. But look on the bright side - at least you didnt drop a beer glass on the floor lika a certain numpty *cough* Nick. :p:

Nice you were looked after though - returning the favour for the other night :wink:

and why did hardly anyone turn up from other colleges? It was us and you guys. Just shows we really are an unsociable subject :s:

Ive heard the end of ninth banded around as a results timetable - although seems early to me. I suspect yours is probably correct.

Feeling better now?

axr + kr = c

and r is?

If a and c are independent then a, c and a x c will form a basis

So any r can be written uniquely in the form

r = Xa + Yb + Z(a x c)

Sub this into the equation and you'll get conditions on X, Y and Z by comparing the coefficients of a, of c, and of axc

thanks guys, am feeling fine now and had a good evening with parents. It's strange having nothing to do now...been doing washing (and my rents took most of my stuff home this morning) and now going to run a few errands etc.

Not sure why no1 from any of the other colleges turned up...especially as the Jesuites invited us to the pub to begin with and I just extended the invitation to loads of other ppl. Oh and well done Nick for dropping the glass - I remember that happening (if not much else!). I've also learnt never to drink on an empty stomach again - I'm not a big drinker and usually 3/4 drinks are all I ever have and I'm always the sober one among my friends, so I suppose it was good to be the other way round for once, although I must admit, I'm reluctant to drink again now after being drunk yesterday; I'll never get drunk again I promise!!!

Anyways, lets hope we all passed (I'm sure you guys did...it's me I'm worried about!!!) and hopefully results will come out relatively soon (but not spoil my bday!!!).
