Subtended

After 12 to 20 months, the stem grows into a spike-like inflorescence up to convert long with over 100 spirally arranged, trimerous flowers, each subtended by a bract.

By the same argument, the maximum solid angle that can be subtended at any point is 4 sr.

Definition Radian describes the plane angle subtended by a circular arc as the length of the arc divided by the radius of the arc.

Definition Section of cone (1) and spherical cap (2) that subtend a solid angle of one steradian inside a sphere A steradian can be defined as the solid angle subtended at the center of a unit sphere by a unit area on its surface.

Each floret may be subtended by a bract, called a "palea" or "receptacular bract".

Equivalently, it is the subtended angle, from that star's perspective, of the semi-major axis of Earth's orbit.

In a constant-angle dam, also known as a variable radius dam, this subtended angle is kept a constant and the variation in distance between the abutments at various levels are taken care of by varying the radii.

In the upper diagram the earth in its orbit sweeps the parallax angle subtended on the sun.

Meridian distance on the sphere On the sphere the normal passes through the centre and the latitude (φ) is therefore equal to the angle subtended at the centre by the meridian arc from the equator to the point concerned.

Once this distance is found, the distance away can be found via the arc subtended in the sky, providing a temporary distance measurement.

Parallax in astronomy Parallax is an angle subtended by a line on a point.

Since the maximum aperture of the pencils issuing from O is the angle u subtended by the entrance pupil at this point, the magnitude of the aberration will be determined by the position and diameter of the entrance pupil.

Size and shape were determined by the visual angle subtended at the eye combined with perceived distance and orientation.

The beam width can be measured in units of length at a particular plane perpendicular to the beam axis, but it can also refer to the angular width, which is the angle subtended by the beam at the source.

The radian measure of angles is the ratio of the length of a circle's arc subtended by an angle whose vertex is the centre of the circle to some other length.

This can be seen from the definition given earlier: the angle subtended at the centre of a circle, measured in radians, is equal to the ratio of the length of the enclosed arc to the length of the circle's radius.

This system specifies the latitude and longitude of any location in terms of angles subtended at the centre of the Earth, using the equator and (usually) the Greenwich meridian as references.
