on page 9 the 2nd worked example for the scalar product it says to calculate AB->.BC->, then the notes work out AB-> and AC-> and get them together to form AB->.AC->

was just wondering if this is correct or there has been a typo or something

Sorry that is a typo, the question should read: calculate AB.AC

I will fix that soon, thanks for pointing it out.

Just some minor things:

I think that using eg rather than e.g. is bad style.

"A 3-D set of axes are represented..." should be "A 3-D set of axes is represented.." (since set is singular).

The arrowheads above the directed line segments are very small - hardly visible when the notes are printed 2 sheets to an A4 page.

Page 5 - "any vector can be written using i, j and k in one of the following ways, for example"
It looks like this supposed to say
"any vector can be written using i, j and k in the following way."
?
