The drag curve or drag polar is the relationship between the drag on an aircraft and other variables, such as lift, the coefficient of lift, angle-of-attack or speed. It may be described by an equation or displayed as a graph (sometimes called a "polar plot"). [1] Drag may be expressed as actual drag or the coefficient of drag.
The data set lists values for each of the variables, such as for example height and weight of an object, for each member of the data set. Data sets can also consist of a collection of documents or files. [2] In the open data discipline, data set is the unit to measure the information released in a public open data repository.
The spin-weighted harmonics are organized by degree l, just like ordinary spherical harmonics, but have an additional spin weight s that reflects the additional U(1) symmetry. A special basis of harmonics can be derived from the Laplace spherical harmonics Y lm , and are typically denoted by s Y lm , where l and m are the usual parameters ...

Once the radius is fixed, the three coordinates (r, θ, φ), known as a 3-tuple, provide a coordinate system on a sphere, typically called the spherical polar coordinates. The plane passing through the origin and perpendicular to the polar axis (where the polar angle is a right angle) is called the reference plane (sometimes fundamental plane).
When it comes to losing weight, there are no shortage of unproven recommendations to choose from: fad diets like the carnivore diet or GOLO diet; juice cleanses and vitamin injections; plus a host ...
Keshon Gilbert scored 16 points, grabbed 10 rebounds and dished five assists as No. 3 Iowa State pulled away from No. 25 Baylor 74-55 in a Big 12 Conference showdown Saturday in Ames, Iowa.
The perceived stupidity of the dodo, a medium-sized flightless bird that was native to Mauritius, is due to naivety and passivity from living in isolation without significant predators. [67] Many believe that the dodo was hunted to extinction by European settlers due to its high culinary value.
