This app uses a specified Lagrange interpolation method to generate a polynomial (straight line) from arrays $x$ and $y$ and approximate the value of this equation at the point say $x = x_{0}$.

1
Array of $x$ values.
2
Array of $y$ values.
3
The variable to use as the unknown in the polynomial.
4
Point at which to approximate the value of the generated polynomial.
5
Whether or not the point $x_{0}$ should be plotted on the graph.
6
Derivative order.
7
Whether or not to plot derivative function.
8
Decimal points to be displayed.
