1) Let f, g, and h be functions defined by f(x) = 1-cosx ", g(x) = x2 sin and x2 h(x) = sin(x) for x # 0. All the following inequalities are true for x # 0. Which X of the inequalities can be used with the squeeze theorem to find the limit of the function as x approaches 0? Justify your answer. (i) (1-x2) Sf (x)s; (ii) -x'sg(x) Sx2 (iii) 1 Sh(x) s
