    This provides the basis for the iterative formula
    [IMG]file:///C:/Users/JOANNA~1/AppData/Local/Temp/msohtmlclip1/01/clip_image001.png[/IMG]Xr+1 = xr3+3
    5.2
    Taking x=1 as a starting point to find the root in the interval (0,1)
    x1=1
    x2=0.7692307692
    x3=0.724852071
    x4=0.716317706
    x5=0.7146764819
    x6=0.7143608919
    x7=0.7143001658
    x8=0.7142884934
    x9=0.7142862487
    x10=0.7142858171
    x11=0.7142857341
    x12=0.7142857181
    x13=0.714285715
    x14=0.7142857144
    x15=0.7142857143
    x16=0.7142857143
    The root is converged to between x15 and x16 A rearrangement is applied successfully to find a root of a third equation.
    1
    Convergence of this rearrangement to a root is
    demonstrated graphically and the magnitude of g
    1
    '(x)
    is discussed.
    1 A rearrangement of the same equation is applied in a
    situation where the iteration fails to converge to the
    required root.
    1 This failure is demonstrated graphically and the
    magnitude of g '(x) is discussed -?This is what is required to do i done the converged but not too sure what I suppose to do now and how to draw a graph with this and what program to use !!!
