Suppose we modify the bisection method into the following variation: for each step, with bracketing interval [a, b], approximations are chosen at the location (2a + b)/3, but the interval is cut into two at the different location (a +3b)/4. (a) Calculate the first 2 approximations co,c for this variation when f(x)cos.- with starting interval [0,2]. (b) Explain why the absolute error of the approximation do is . Then similarly bound the absolute errors of the approximations cn

For each n E N, define a function fn A - R. Suppose that each function fn is uniformly continuous. Moreover, suppose there is a function f : A R such that for all є 0, there exists a N, and for all x E A, we have lÍs(x)-f(x)|く for all n > N. Then f is uniformly continuous. Note: We could say that the "sequence of functions" f "converges to the function" f. These are not defined terms for...
