In-orbit rendezvous is a key enabling technology for many space missions.

By changing the display options, we can see that the basis vectors are tangent to the corresponding coordinate lines. Spherical coordinates are defined with respect to a set of Cartesian coordinates, and can be converted to and from these coordinates using the atan2 function as follows. To convert from Cartesian coordinates, we use the same projection and read off the expressions for the spherical coordinates. If the spherical coordinates change with time then this causes the spherical basis vectors to rotate with the following angular velocity.

Spherical coordinate system

These statements are based on the observations that Earth is nearly a sphere and that the depth of the atmosphere or at least the depth over which the bulk of its mass lies is small in comparison to Earth's mean radius. From at least a theoretical point of view, however, it would be desirable to derive the equations of atmospheric motion taking into account the earth's equational bulge caused by the earth's rotation , and then to make a systematic comparison with the spherical formulation. Although all of the global models currently used to simulate the atmospheric general circulation and climate are based on the spherical approximation, this is probably not the cause of the models' major errors. In addition to the further approximations introduced by the widely used hydrostatic assumption and the so-called traditional approximation, more significant errors are introduced by the models' parameterizations of physical processes and by the numerical approximations used in their solution. Nevertheless, systematic errors due to model formulation should be investigated. Although the spheroidal equations may be derived in several ways, the strategy to be followed here involves coordinate transformation based upon the theory of generalized curvilinear coordinates in an effort to make the derivation as transparent and objective as possible.

If you make a print-out, you should be aware that some printers apparently do not print Greek letter symbols in boldface, even though they appear in boldface on screen. You should be on the look-out for this. If in doubt, look at what appears on the screen. We shall find expressions for the rate at which the unit radial and transverse vectors are changing with time. Being unit vectors, their magnitudes do not change, but their directions do.

Приступайте. - Мы не успеем! - крикнула Соши.  - На это уйдет полчаса.

В попытке сохранить равновесие он резко выбросил руки в стороны, но они ухватились за пустоту. Внезапно он взвился в воздух и боком полетел вниз, прямо над Беккером, распростертым на животе с вытянутыми вперед руками, продолжавшими сжимать подсвечник, об который споткнулся Халохот. Халохот ударился сначала о внешнюю стену и только затем о ступени, после чего, кувыркаясь, полетел головой .

Это. - подумала она удивленно и с облегчением и попыталась выскользнуть из-под. - Милый, - глухо прошептала.  - Позволь, я переберусь наверх.  - Но немец даже не шевельнулся. Росио изо всех сил уперлась руками в его массивные плечи.

 В этом и заключается его замысел. Алгоритм есть уже у. Танкадо предлагает ключ, с помощью которого его можно расшифровать. - Понятно.  - Она застонала. Все четко, ясно и. Танкадо зашифровал Цифровую крепость, и только ему известен ключ, способный ее открыть.

Грязь, в раковине мутная коричневатая вода. Повсюду разбросаны грязные бумажные полотенца, лужи воды на полу. Старая электрическая сушилка для рук захватана грязными пальцами. Беккер остановился перед зеркалом и тяжело вздохнул. Обычно лучистые и ясные, сейчас его глаза казались усталыми, тусклыми. Сколько я уже тут кручусь. Однако считать ему не хотелось.

    In mathematics , a spherical coordinate system is a coordinate system for three-dimensional space where the position of a point is specified by three numbers: the radial distance of that point from a fixed origin, its polar angle measured from a fixed zenith direction, and the azimuthal angle of its orthogonal projection on a reference plane that passes through the origin and is orthogonal to the zenith, measured from a fixed reference direction on that plane.
