The Lorentz
transformations at the heart of special relativity are just
hyperbolic rotations. We outline here how to use
"hyperbolic triangle trig" to solve problems in special
relativity.
This approach to special
relativity grew out of class notes for a
course on Reference Frames, which in turn forms part of a major
upperdivision curriculum reform effort, the Paradigms in Physics
project [1], begun in the Department of Physics at Oregon State
University
in 1997, and supported in part by NSF grants DUE{965320 and DUE{0231194.
This presentation is largely excerpted from a
book in
preparation, where further details can be found, and has
also appeared in The Physics Teacher.
