Constructed the Lagrange interpolating polynomial that interpolates f(x)=cos(x) on the interval [0, 2π] using 6 Chebyshev nodes. The coefficients of the polynomial are meticulously computed, followed by a graphical comparison with the original function to visually affirm the accuracy of the interpolation….
