3. 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 !!!
