Quaternions
Overview
Quaternions are algebraic objects, similar to complex numbers, where in addition to the normal
real numbers, are defined three new numbers, {% i %}
{% j %}
{% k %}
which satisfy the following algebraic rules.
{% i^2 = j^2 = k^2 = ijk = -1 %}
Then a general quaternion is defined as a sum of four terms.
{% z = a + bi + cj + dk %}
