- (5 points) Assume you have computed = co+cr. Compute the relative error in evaluating this function (i.e., evaluate the impact of finite precision on the result). Do not bound. Assume: all error originates from representing co, C1, and x. arithmetic operations introduce no error. Start with @* = c +(*)8 (5 points) Continue the previous problem. Derive an upper bound for the relative error of = co +cix". Consider defining Emaz = max(|0|, |61|, |2,..., En)
