| 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. |
