and the axis rises from the horizontal position to a series of cusps; and the mean precessional motion is the same as in steady motion with the same rotation and the axis horizontal.
The special case of f = ½ may be stated here; it is found that
| p | exp (ῶ − pt) i = √ | (1 + x) (κ − x) | + i √ | (1 − x) (κ + x) | , |
| a | 2 | 2 |
