Arguments definition
Marker1 |
The name or argument number of a marker to be calculated. |
Marker2 |
The name or argument number of a marker to be calculated. • If omitted, then the InertiaMarker is applied. |
Formulation
In line with the sequentially defined rotation order, return rotation angle θ on the x-axis, which is the second rotation.
