In this paper, an expansion of the classical hyperbolic functions is presented and studied. Also, many features of the k- Pell hyperbolic functions are given. Finally, some graph and curved surfaces related to the k − Pell hyperbolic functions are introduced.

In this article, we study the wellposedness of the inverse problem for Sturm-Liouville equation with coulomb potential. We will consider two different inverse problem for Sturm-Liouville equation with coulomb potential. We will prove that ıf the spectral characteristics of this problems are close to each other, then the difference between their potential functions is sufficiently small.
