Lou,

as for your confusion about where "acos()" came from:

You are right that if you do:

from math import *
and
from numpy import *

numpy will override some of the math functions, but not "acos()", 
because numpy has "arccos()" function instead.

And all of this is a good reminder to not use "import *"

import numpy as np

is the most common way to import numpy these days -- yes it reasults in 
a bit of extra typing, but "namespaces are one honking great idea":
