Abstract

This article analyzes the properties of trigonometric functions in the Galilean
and Minkowski planes. In Galilean geometry, space and time are independent, and
the classical trigonometric functions ( pinx, posx, ptgx, ⁡pctgx ) are used in a slightly
different way. In Minkowski geometry, the space-time interval is defined based on
the theory of relativity, and hyperbolic trigonometric functions ( shx, chx, thx, cthx)
are used. This differences space-time concepts physicist basics and their
mathematician to be expressed deeper to understand help gives .
