This leads to an important generalization: a ﬁnite subset X of Sn−1 is called a spherical ψ-code if for every pair (x,y)ofX the inner product x·y ≤ cosψ; i.e., the minimal angular separation is at least ψ. Spherical codes have many applications. give crossword puzzle

The Angular … WebThe Haversine (or great circle) distance is the angular distance between two points on the surface of a sphere. The first coordinate of each point is assumed to be the latitude, the second is the longitude, given in radians. The dimension of the data must be 2. WebRemember also that spherical coordinates use ρ, the distance to the origin as well as two angles: θthe polar angle and φ, the angle between the vector and the zaxis. The coordinate change is T: (x,y,z) = (ρcos(θ)sin(φ),ρsin(θ)sin(φ),ρcos(φ)) . The integration factor can be seen by measuring the volume of a spherical wedge which is give crown to shyka
