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 ?
) Find the Chebyshev interpolating polynomial that attains the values 6, 1, 3, and 66 at the points −1, 0, 2 and 6. Reduce the polynomial to its natural form.
