Angle

Computes the angle between two objects. If geometry_status=2, then angle=angle2d; if geometry_status=3, then angle=angle3d.

Description

Computes the angle between a conic and the line {y=0}. For instance, if the conic is an ellipse, the angle computed is the angle formed by the line passing through the focus and the horizontal axis. If the conic is a parabola, the axis of symmetry is considered.
