Lagrange Interpolation Formula for nth Order
The Lagrange Interpolation formula for nth degree polynomial is given below:
Lagrange Interpolation Formula for the nth order is,
Lagrange First Order Interpolation Formula
If the Degree of the polynomial is 1 then it is called the First Order Polynomial. Lagrange Interpolation Formula for 1st order polynomials is,
Lagrange Second Order Interpolation Formula
If the Degree of the polynomial is 2 then it is called Second Order Polynomial. Lagrange Interpolation Formula for 2nd order polynomials is,
Lagrange Interpolation Formula
Lagrange Interpolation Formula finds a polynomial called Lagrange Polynomial that takes on certain values at an arbitrary point. It is an nth-degree polynomial expression of the function f(x). The interpolation method is used to find the new data points within the range of a discrete set of known data points.
