Abstract

The functional equation , satisfied by the three angles  and  of a non-degenerate triangle, was  shown  to characterize the tangent function by Benz in 2004.  This result has been generalized by the authors to a functional equation, with  parameters representing the angles of a non-degenerate convex -gon. Here, it is shown that there are other different but similar functional equations characterizing the tangent function. 

Keywords: functional equation; tangent function; convex polygon
