The reference directions of the individual variables are not important, only their relation to each other.

This is called the reference direction for current i.

Consequently, the reference directions of currents are often assigned arbitrarily.

It is simply a convenient uniform measure of how far around its orbit a body has progressed since passing the reference direction.

Note that you usually need to give units, and that the angle must be measured relative to a reference direction.

Diameter of a cylinder is usually measured in the marked reference direction across the circle, taken at three elevations.

Isoclinics are curves on which the principal axes make a constant angle with a given fixed reference direction.

Polarised atoms of xenon are useful because they can provide the reference direction for very accurate gyroscopes.

The body x-axis does not align with the velocity vector, which is the reference direction for wind axes.

Reference direction is the primary beam (label: X-ray).

Neither direction corresponds to the appropriate palaeomagnetic reference direction for the Miocene.

If a reference direction from one side of the plane of reference to the other is defined, the two nodes can be distinguished.

The reference direction, stated first, is always north or south, and the turning direction, stated last, is east or west.

Maintenance of a desired orientation of a vehicle or device with respect to one or more reference directions. stable element.

The grand mean direction is statistically indistinguishable from the three Miocene reference directions, suggesting that there has been no footwall tilting.

If the inclination is 0, there is no ascending node, so ω is measured from the reference direction.

If navigating by gyrocompass, the reference direction is true north, in which case the terms true bearing and geodetic bearing are used.

In land navigation, a bearing is ordinarily calculated in a clockwise direction starting from a reference direction of 0 and increasing to 359.9 degrees.

Define as the longitude of the pericenter, the angular distance of the pericenter from a reference direction.

A satisfactory agreement is found instead with Cretaceous – early Cenozoic North America cratonic reference directions.

Animals associate the sun azimuth with time of day provided by their internal clock and a reference direction provided by their magnetic compass.

The optical axis of the TEM is then analogous to the reference direction of an optical goniometer.

It is the angle from a reference direction, called the origin of longitude, to the direction of the ascending node, measured in a reference plane.

In navigation, the word bearing is used for different methods that try to find out the angle between an object used for this purpose, and a reference direction.

If the reference direction is north (either true north, magnetic north, or grid north), the bearing is termed an absolute bearing.
