https://en.wikipedia.org/wiki/Runge's_phenomenonIn the mathematical field of numerical analysis, Runge's phenomenon is a problem of oscillation at the edges of an interval that occurs when using polynomial interpolation with polynomials of high degree over a set of equispaced interpolation points. It was discovered by Carl David Tolmé Runge(1901) when exploring the behavior of errors when using polynomial interpolation to approx…

Note the oscillations in the interpolant which renders it basically useless for interpolation as an
