Feb 9, 2024 · 1 This is a different approach than the ones in Proof of relation between divided difference and interpolation polynomial coefficient. Possibly unnecessarily complex, but it gets the job done.

Oct 12, 2013 · Can anybody explain to me what Lagrange Interpolating Polynomial is with examples? I know the formula but it doesn't seem intuitive to me.

Feb 18, 2018 · Is there a bound on how many roots a multivariate polynomial can have? Furthermore, for this intuition I assumed that the polynomials agree on some specific points.

Jul 26, 2013 · What is the difference, if any, between spline interpolation and piecewise polynomial interpolation?

Dec 14, 2022 · It is possible to use interpolation to approximate the Taylor series expansion of a function, but it is not the only way to do so. In general, the Taylor series of a function can be found by …

Feb 24, 2022 · This is a toy example (obviously the constant $1$ polynomial interpolates these two points) but it showcases the problems with lagrange interpolation over rings that aren't integral domains.

Between 2 points, the interpolation is by a line segment, i.e., a linear function. Using four points gives a cubic interpolation polynomial. Check again the formulas for Lagrange interpolation.
