a) Find the largest real root of
lying between 1 and 2. Perform three iterations by
i) bisection method
ii) secant method
To solve numerically for the largest real root of the equation \( f(x) = x^6 - x - 1 = 0 \) lying between 1 and 2, we can use two methods: the Bisection Method and the Secant Method. ### 1) Bisection Method The Bisection method requires us to have two initial guesses, \( x_0 = 1 \) and \( x_1 = 2 \), such that \( f(x_0) \) and \( f(x_1) \) have opposite signs. ____ ______ _________ ______ ___ ____ ________ ____ ____.
