rapidities's Usage Examples:

ordinary rotation angle variables θ j {\displaystyle \theta ^{j}} and three rapidities η j {\displaystyle \eta ^{j}} .

a Euclidean triangle of velocities, we get a Lobachevski triangle of rapidities".

In terms of the rapidities, the rotation angle θ is given by tan ⁡ θ 2 tanh ⁡ ζ x 2 tanh ⁡ ζ y.

the fixed-target experiments pentaquarks will be produced with small rapidities in laboratory frame and will be easily detected.

expressing products on the unit hyperbola illustrates the additivity of rapidities for collinear velocities.

of the selling or buying agents with algebraically increasing bargain rapidities and volumes.

E {\displaystyle k_{AE}k_{AB}k_{BE}} , that the composition rule for rapidities is addition: φ A E φ A B + φ B E .

American (Feb 2008) 54–59 This velocity-addition rule is easily derived from rapidities α and β, since sinh(α + β) cosh α cosh β (tanh α + tanh β).

b     w / c {\displaystyle \tanh \ b\ \ w/c} , so that a and b are rapidities corresponding to velocities v and w.

{\displaystyle \left[\xi ,\ \eta ,\ \zeta \right]} with relativistic rapidities ( [ U c ,   v c ,   u c ] [ tanh ⁡ ξ ,   tanh ⁡ η ,   tanh ⁡ ζ ] ) {\displaystyle.

model) is given by in which the rapidity can be composed of arbitrary many rapidities η 1 , η 2 … {\displaystyle \eta _{1},\eta _{2}\dots } as per the angle.

For one-dimensional motion, rapidities are additive whereas velocities must be combined by Einstein"s velocity-addition.
