As is well known, the common elementary functions defined over the real
numbers can be generalized to act not only over the complex number field but
also over the skew (non-commuting) field of the quaternions. In this paper, we
detail a number of elementary functions extended to act over the skew field of
Clifford multivectors, in both two and three dimensions. Complex numbers,
quaternions and Cartesian vectors can be described by the various components
within a Clifford multivector and from our results we are able to demonstrate
new inter-relationships between these algebraic systems. One key relationship
that we discover is that a complex number raised to a vector power produces a
quaternion thus combining these systems within a single equation. We also find
a single formula that produces the square root, amplitude and inverse of a
multivector over one, two and three dimensions. Finally, comparing the
functions over different dimension we observe that $ C\ell \left (\Re^3 \right)
$ provides a particularly versatile algebraic framework.
