On the interval [-1,1], consider interpolating Runge’s function
f(x) = 1/ (1 + 25x^2) By Pn(x), use computer to graph:
(c) Take 11 equally spaced nodes in [-1,1], starting at –1,
ending at 1, and obtain the interpolating polynomial P10(x). Also,
use 11 Chebyshev nodes in [-1,1] and obtain Pc(x), the
corresponding interpolating polynomial. In the same graph, plot the
three functions f(x), P10(x) and Pc(x) over the interval [-1,1] .
Use different line-styles, so that f(x), P10(x) and Pc(x)...
