Abstract. In this paper is given the problem of interpolation functions at general and of the interpolation function of Lagrange in particular. With some concrete examples is made illustration of finding interpolation polynomial with Lagrange method, then was introduced an application software that is used quite for solving a lot of math problems, WolframMathematica, which quickly and accurately makes finding interpolation requested polynomial.

Finally with the same application software, which has the power of programming in it, I developed a program that most clearly shows the form of getting the interpolation polynomial of Lagrange, depending on number $n$ and the points $x_{i}$ and $y_{i} $ for $i\le n$.
