$2\mathrm{.}3.$ c let us try to find $51/3$ by the fixed$-$point method. use the fact that the result must be the positive solution of f$($x$)=$ x $35=0$ to solve the following: $($a$)$ introduce two different fixed$-$point forms which are convergent for x in $[1,2].($b$)$ perform five iterations for each of the iterations with p$0=1\mathrm{.}5,$ and measure $|$p $$ p$5|.($c$)$ rank the associated iterations based on their apparent speed of convergence with p$0=1\mathrm{.}5.$ discuss why one is better than the other.
