Derive newton's forward interpolation formula
WebPolynomial interpolation involves finding a polynomial of order n that passes through the n 1 points. One of the methods of interpolation is called Newton’s divided difference polynomial method. Other methods include the direct method and the Lagrangian interpolation method. We will discuss Newton’s divided difference polynomial …
