Lagrange Interpolation
Lagrange interpolating polynomial effective that they uniformly approximate continuous functions. This calculator will interplolate your given data.

Pn(x) =anxn +an−1xn−1 +···+a1x+a0

How to use this calculator?
1. Set number of degrees that you need to interpolate.
2. Put points value. So that, (X[1], F[1])
3. Set F[4] for error calculation.

Result: According to Lagrange interpolating, you will get the value of P(X):
degree of interpolation: just write a number
