Hi,
in the method -Theory of Fixed Point Iteration of x = g(x)
If the function g(x) has several roots, why sometimes we need to change the form of g(x) to find the other roots?
For example we can have x3+3x2+x+4,
one form can be x= -x3-3x2-4
or
another form can be
x=sqrt(-x3-3x2-4) / sqrt (3)
those two forms converge into diffrent values.WHY?
Thank you
Brad
