Mechanics Of Planar Particle Motion - Fictitious Forces in A Local Coordinate System
... To introduce the unit vectors of the local coordinate system shown in Figure 1, one approach is to begin in Cartesian coordinates in an inertial framework. 1) This displacement is necessarily tangent to the curve at s, showing that the unit vector tangent to the curve is while the outward unit vector normal to the curve is Orthogonality can be ... The unit magnitude of these vectors is a consequence of Eq ...
Unit Length
... In mathematics, a unit vector in a normed vector space is a vector (often a spatial vector) whose length is 1 (the unit length) ... A unit vector is often denoted by a lowercase letter with a "hat", like this (pronounced "i-hat") ... In Euclidean space, the dot product of two unit vectors is simply the cosine of the angle between them ...
Optical Properties Of Carbon Nanotubes - Electronic Structure of Carbon Nanotube
... The indices refer to equally long unit vectors at 60° angles to each other across a single 6-member carbon ring ... the origin as carbon number 1, the a1 unit vector may be considered the line drawn from carbon 1 to carbon 3, and the a2 unit vector is then the line drawn from carbon 1 to carbon 5 ... the diagram at right.) To visualize a CNT with indices (n, m), draw n a1 unit vectors across the graphene sheet, then draw m a2 unit vectors at a 60° angle to the a1 vectors, then add the vectors together ...
Clifford Algebra - Spinors - Real Spinors
... is the set of invertible elements in Cℓp, q which can be written as a product of unit vectors Comparing with the above concrete realizations of the Clifford algebras ... of those elements of Pinp, q which are products of an even number of unit vectors ... is given by the mapping v ↦ −v acting on pure vectors ...
Poincaré Disk Model - Angles
... the angle between the circular arc whose endpoints (ideal points) are given by unit vectors u and v, and the arc whose endpoints are s and t, by means of a formula ... that v = −u and t = −s, then we are merely finding the angle between two unit vectors, and the formula for the angle θ is If v = −u but not t = −s, the formula becomes, in terms of the wedge product ...

### Famous quotes containing the word unit:

During the Suffragette revolt of 1913 I ... [urged] that what was needed was not the vote, but a constitutional amendment enacting that all representative bodies shall consist of women and men in equal numbers, whether elected or nominated or coopted or registered or picked up in the street like a coroner’s jury. In the case of elected bodies the only way of effecting this is by the Coupled Vote. The representative unit must not be a man or a woman but a man and a woman.
George Bernard Shaw (1856–1950)
