Lagrange interpolating polynomial effective that they uniformly approximate continuous functions.
This calculator will interplolate your given data.
Pn(x) =anxn +an−1xn−1 +···+a1x+a0How to use this calculator? 1. Set number of degrees that you need to interpolate. 2. Put points value. So that, (X, F) 3. Set F for error calculation. Result: According to Lagrange interpolating, you will get the value of P(X):
