The calculator calculates the Lagrange polynomials and the interpolation polynomial for any definable points. The points can be entered in tabular form or alternatively loaded from a file.
An alternative input is possible by loading the data from a file. The values must be separated by comma, space or semicolon and must be in pairs x1, y1, x2, y2, ...
The individual Lagrange polynomials are:
The Lagrange interpolation polynomial is:
