An azimuth (i/ˈæzɪməθ/; from Arabic السمت as‑samt, meaning "a way, a part, or quarter") is an angular measurement in a spherical coordinate system that is calculated by perpendicularly projecting the vector from an observer (origin) to a point of interest onto a reference plane and measuring the angle between it and a reference vector on the reference plane.
An example of an azimuth is the measurement of the position of a star in the sky. The star is the point of interest, the reference plane is the horizon or the surface of the sea, and the reference vector points to the north. The azimuth is between the north point and the perpendicular projection of the star down onto the horizon.
Azimuth is usually measured in degrees (°). The concept is used in many practical applications including navigation, astronomy, engineering, mapping, mining and artillery.
In land navigation, azimuth is usually denoted as alpha, Failed to parse (Missing texvc executable; please see math/README to configure.): \alpha , and defined as a horizontal angle measured clockwise from a north base line or meridian.Azimuth has also been more generally defined as a horizontal angle measured clockwise from any fixed reference plane or easily established base direction line.
Breathe again, Delilah's gone
Upped and took the piano
Oh you and I have never been older
Oh you and I have never been older
Sure as I was standing there
She was mine until I cared
Oh you and I have never been older
Oh you and I have never been older
How can you say you are lonely
Oh when you've got my baby?
Call off the fire you owe me
And breathe again
Certain times define a face
So I'm left to kiss a trace
Breathe again, Delilah's gone
Breathe again, Delilah's gone
How can you say you are lonely
Oh when you've got my baby?
Call off the fire you owe me
