Q2 2015
a) show that the function f(x) = pi/2-x-sin(x)
has at least one root x* in the interval [0,pi/2]
b)in a fixed-point formulation of the root-finding problem, the
equation f(x) = 0 is rewritten in the equivalent form x = g(x).
thus the root x* satisfies the equation x* = g(x*), and then the
numerical iteration scheme takes the form x(n+1) = g(x(n))
prove that the iterations converge to the root, provided that
the starting...
