The method of Hurwitz-Radon Matrices (MHR) enables interpolation of two-dimensional curves using different coefficients [gamma]: polynomial, sinusoidal, cosinusoidal, tangent, cotangent, logarithmic, exponential, arcsin, arccos, arctan, arcctg or power function [16], also inverse functions.
I've also been able to use visuals in some of my limited editions, and you've seen some of the book objects that I've done through CoTangent Press, like The Happy Girts and The Convict Bird.
The latest child of his CoTangent Press, a small publishing operation devoted to artists' editions of selected Vollmann works, is The Happy Girls, based on a tale from Thirteen Stories and Thirteen Epitaphs.
Toller [73] has explored the different possible geometries associated with the maximal acceleration principle and the physical implications of the meaning of an "observer", "measuring device" in the cotangent space.
The relations (151, 152, 153, 154, 155) are required in order to prove the group composition law of the transformations of (137)-(140) and, consequently, in order to have a truly Maximal-Acceleration Phase Space Relativity theory resulting from a phase-space change of coordinates in the cotangent bundle of spacetime.
Police officials called heavy cotangents of the force to control the unruly mobs who set on fire several houses in the locality.
We appreciate the helpful cotangents and insight of the reviewer who brought this to our attention.
