polinominterpoláció
Polinominterpoláció is a method used in numerical analysis to find a polynomial that passes through a given set of data points. Given a set of $n+1$ distinct data points $(x_0, y_0), (x_1, y_1), \dots, (x_n, y_n)$, the goal of polynomial interpolation is to find a unique polynomial $P(x)$ of degree at most $n$ such that $P(x_i) = y_i$ for all $i = 0, 1, \dots, n$. This polynomial is called the interpolating polynomial.
There are several ways to construct the interpolating polynomial. The Lagrange form of the interpolating polynomial
Polynomial interpolation is a fundamental concept with applications in curve fitting, function approximation, and solving differential
