I am using 2018 maple(maple 18).

F := proc (x) options operator, arrow; x-2*f(x)/(D(f))(x) end proc

 

algsubs(f(c) = 0, F(c))

algsubs(f(c) = 0, (D(F))(c))

algsubs(f(c) = 0, (D(D(F)))(c))

proc (x) options operator, arrow; x-2*f(x)/(D(f))(x) end proc

c

2*((D@@2)(f))(c)/(D(f))(c)

if we put m=2, then the order of convergence must be 2 but maple shows the order of convergence one.

 

Please gives answer
