Assume you have computed = .

a). Compute the relative error in evaluating this function (i.e., evaluate the impact of finite precision on the result).

Assume that all error originates from representing . Assume arithmetic operations introduce no error.

Start with () ^ = .

b). Continue the previous problem. Derive an upper bound for the relative error of

= .

Consider defining

C1, C, and r C1, C, and r
