Rezumat:

Using the algebraic theory of trigonometric polynomials, two methods to obtain cubic trigonometric spline functions of interpolation are presented. Periodic and non-periodic cubic trigonometric spline functions are considered. As an application in approximate integration, two quadrature formulas are also obtained (For details see the preprint on the Web page.)
