Normal coordinates exist on a normal neighborhood of a point p in M. A normal neighborhood U is an open subset of M such that there is a proper neighborhood V of the origin in the tangent space T p M, and exp p acts as a diffeomorphism between U and V. On a normal neighborhood U of p in M, the chart is given by: :=: The isomorphism E, and ...
The provinces of Vietnam are subdivided into second-level administrative units, namely districts (Vietnamese: huyện), provincial cities (thành phố trực thuộc tỉnh), and district-level towns (thị xã).
Geodetic latitude and geocentric latitude have different definitions. Geodetic latitude is defined as the angle between the equatorial plane and the surface normal at a point on the ellipsoid, whereas geocentric latitude is defined as the angle between the equatorial plane and a radial line connecting the centre of the ellipsoid to a point on the surface (see figure).
If itself is a geodesic, then Fermi–Walker's transport becomes the standard parallel transport and Fermi's coordinates become standard Riemannian coordinates adapted to . In this case, using these coordinates in a neighbourhood T {\displaystyle T} of γ {\displaystyle \gamma } , we have Γ b c a = 0 {\displaystyle \Gamma _{bc}^{a}=0} , all ...

In geometry, a normal is an object (e.g. a line, ray, or vector) that is perpendicular to a given object. For example, the normal line to a plane curve at a given point is the line perpendicular to the tangent line to the curve at the point. A normal vector of length one is called a unit normal vector.
Homogeneous coordinates are not uniquely determined by a point, so a function defined on the coordinates, say (,,), does not determine a function defined on points as with Cartesian coordinates. But a condition f ( x , y , z ) = 0 {\displaystyle f(x,y,z)=0} defined on the coordinates, as might be used to describe a curve, determines a condition ...
Quách Thị Trang Square (Vietnamese: Công trường Quách Thị Trang) is the city square in front of the well-known Bến Thành Market in District 1, downtown Ho Chi Minh City, Vietnam. [ 1 ] The square was known for its landscaped traffic circle featuring the equestrian statue of Trần Nguyên Hãn [ vi ] and the white bust of Quách ...
