Hi,
Just a quick question and one which I'm sure I'm just being thick not being
able to do but I have come across a problem in my notes for a Msc course I
am doing shown below and I don't understand the Maths behind how one step
moves to the next. I know there's probably some simple rules I am
forgetting.
<<...OLE_Obj...>>
I can understand the exponential part, where an exp term divided by an exp
term becomes the top term + the bottom term but I don't understand what
happens to the rest of the terms.
Can anyone help and let me know what I'm missing?
Regards
Louise
