Iain, I think I understand where you might get confused: lets start with a
simple example:
Using (u×)3 = – u× , we obtain the modern expression of the Olinde-Rodrigues
formula:
exp(æ u×) = 1 + sin æ u× + (1 – cos æ)
(u×)2,
exp(æ u×) (NM) = (NM) + sin æ u×(NM) + (1 – cos æ)
u× [u×(NM)].
where:
A purely translational displacement T requires a special formulation:
M —> M' = T M = M + T,
SO, what I do is apply this:

there..... isn't that better?
OK, look here is the deal... I've already done the calum ball joke and NO ONE
mentioned it!!!
so unless I get a reply saying how funny the Calum Ball web page is (which I
blatantly stole) then I will do something drastic and make sure I mention the
calum ball web page in every post!!!
govern yourself accordingly
Chris
