    Talking Root Finding

    Please help..

    Find a numerical approximation to the intersection between two functions

    X=1.984/ln(x)


    Starting from x_0=2.400 at k=0 by forming a convergent Fixed Point Iteration, other than Newton’s method . Demonstrate that the fixed point convergence criterion is satisfied near x_0. Tabulate

    k 0 1 2 3
    X_k

    For k= 0 to 3 iterations.

    Re: Root Finding

    Okay, what is your difficulty? If you understand what a "fixed point iteration" is this is pretty easy.
    With x_0= 2.4, x_1= 1.984/ln(2.4)= 2.266. Then x_2= 1.984/ln(2.266), etc.

    What does your textbook give as the "fixed point convergence criterion"?
    Thanks from topsquark
