Assignment $3$

$3\mathrm{.}1$ Enter: format long. Use mynewton.m on the function $f(x)=x^5-2,$ with $x_0=1.$ By trial and error, what is the lowest value of $n$ for which the program converges $($stops changing$).$ Compute the error, which is how close the program's answer is to the true value. Compute the residual, which is the program's answer plugged into $f.$
