Question

(a) Use Newton’s method with  x1 =1to find the root of
the equation x3 - x  =1correct to six decimal places.
(b) Solve the equation in part (a) using x1 =0.6 as the initial
approximation.
(c) Solve the equation in part (a) using x1=0.57 . (You
definitely need a programmable calculator for this
part.)
; (d) Graph f(x) =x3 -x -1 and its tangent lines at x1 =1
, 0.6, and 0.57 to explain why Newton’s method
is so sensitive to the value of the initial approximation.
