The base vectors e; span a three-dimensional space (indices = 1, 2 or 3) as shown in the sketch.
This is a non-standard coordinate system in which the magnitudes of e, and ez are both 1, but the
magnitude of e2 is 2. Also, the angle between e, and ezis a/4. The angle between ez and both
e, and e, is a/2. A vector y referred to this basis is given by y = 1e, + 1ę2 + 2ę3
