MHB Numerical Analysis: Interpolating Polynomial

AI Thread Summary
Runge's phenomenon refers to the issue of oscillation that occurs when using high-degree polynomial interpolation at equidistant points, leading to significant errors at the edges of the interval. This phenomenon highlights the limitations of polynomial interpolation, particularly in approximating functions that are not well-represented by such polynomials. The discussion includes links to articles that provide further insights into the mathematical principles and implications of Runge's phenomenon. Understanding this concept is crucial for those involved in numerical analysis and interpolation methods. Proper techniques, such as using Chebyshev nodes, can mitigate the effects of Runge's phenomenon.

Hello Everyone,

Actually i would like to have a clear Explanation about Runge Phenomenon.

Could you help me Please.

Seemingly by some mathematical coincidence, a hexagon of sides 2,2,7,7, 11, and 11 can be inscribed in a circle of radius 7. The other day I saw a math problem on line, which they said came from a Polish Olympiad, where you compute the length x of the 3rd side which is the same as the radius, so that the sides of length 2,x, and 11 are inscribed on the arc of a semi-circle. The law of cosines applied twice gives the answer for x of exactly 7, but the arithmetic is so complex that the...
