I've been trying to write some macros that need to analyze vectors and
perform operations on them, but, having absolutely no math background
whatsoever, I am getting way lost in the function explanations in the docs.

Is there somewhere I can find explanations and/or examples of them that are
understandable by us regular folk?

Along the same lines, it's obvious that a little trig could go a long way in
POV. Can someone recommend a beginning book or reference on trigonometric
functions that can be handled by a non-mathmatical sub-genious? Something
that at least explains all the terms used in the docs?
