We could use a linear interpolation algorithm to estimate the value of f(x) at plot point x Sep, or x 2 that appears within the existing data range. Criticism of Interpolation .

Polynomial interpolation to analytic functions can be very accurate, depending on the distribution of the interpolation nodes. However, in equispaced nodes and the like, besides being badly ...
