Abstrakt:

Periodic function – this is a proposition of the new definition – has as its domainthe multiplicative group T = z  C : z = 1 of complex numbers with module one. Therefore a graph of the function f : T  R lies on the cylinder T  R, and so the graph of cosinefunction is the ellipse2212x  y .
