This function is used to calculate the angle between two any-dimensional vector
valued functions.

Here is the syntax:
arc(r1(t), r2(t))
where r1(t) and r2(t) are the vector-valued functions

EXAMPLE:
Find the angle between the 3-dimensional vector valued functions
<t,t,t> and <t,t^2,t^3> at the point (1,1,1)

Solution: Because the point (1,1,1) corresponds to when t=1...
Just type:
ang([t,t,t],[t,t^2,t^3])    [ENTER]
ans(1)|t=1                  [ENTER]
This returns:
arccos(sqrt(42)/7)    (which is about 22.21 Deg)
