WebJul 9, 2024 · Spherical, or surface, harmonics can be further grouped into zonal, sectoral, and tesseral harmonics. Zonal harmonics correspond to the m = 0 modes. In this case, one seeks nodal curves for which Pℓ(cosθ) = 0. Solutions of this equation lead to constant θ values such that cosθ is a zero of the Legendre polynomial, Pℓ(x). WebMar 24, 2024 · Spherical Geometry The study of figures on the surface of a sphere (such as the spherical triangle and spherical polygon ), as opposed to the type of geometry studied in plane geometry or solid geometry. In spherical geometry, straight lines are great circles, so any two lines meet in two points. There are also no parallel lines.
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 … See more To define a spherical coordinate system, one must choose two orthogonal directions, the zenith and the azimuth reference, and an origin point in space. These choices determine a reference plane that contains … See more Just as the two-dimensional Cartesian coordinate system is useful on the plane, a two-dimensional spherical coordinate system is useful on the surface of a sphere.
