Determine the maximum error in quadratic interpolation at equispaced points ?
Perform iterations of Newton-Raphson method to approximate a root of the

equation f(x) = x⁴ - x³ + x - 1 = 0, until the roots at successive iterations are

closer than 10⁻⁵

. How many iterations do you need for this much accuracy ?
(a) Using the formula Tn(x) = cos(n cos−1 x), n ≥ 0, find the Chebyshev

polynomials T0(x), T1(x), T2(x), T3(x), and T4(x).
Using the starting value 2(1 + i ), solve

x4 − 5x3 + 20x2 − 40x + 60 = 0 by Newton-Raphson method, given that all the roots of the given equation are complex.
