Question
(a) Given f (x) = x-e* on [0, 1], with reference to the Bisection Method, determine
the minimum number of iterations required to have an accuracy of 10-9 in the
root. If no root exists on the interval, then write "No root exists."
(b) Given f (x) = x – e=", use the Bisection Method to approximate a root of f on
[0, 1], accurate to 4 decimal digits. If no root exists on the interval, then write
"No root exists."
(c) Given f: R → R, suppose that f is differentiable and |f' (x)| < 1 for all r € R.
Show that the sequence generated by the fixed point iteration method applied
to f converges to a fixed point of f for any initial roER.
(d) Apply the fixed point iteration to cos a – x = -1 four times, with xo = }. Use
an accuracy of 6 decimal digits throughout.
(e) Determine if the fixed point iteration applied in the previous question will con-
verge.
