1.4. Consider the problem of evaluating the function sin(z), in particular, the propagated data error, i.e., the error in the function value due to a perturbation h in the argument x. (a) Estimate the absolute error in evaluating sin(r) (b) Estimate the relative error in evaluating sin(x) (c) Estimate the condition number for this prob- lem (d) For what values of the argument z is this prob lem highly sensitive
