1. Determine the largest root in the interval [2, 5 of f(x) = e-r2 + sin x (a) by using MATLAB to plot y = f(x) over the given interval. As part of your answer include a printout of the graph. (b) using the Bisection method (by hand) and four iterations on the interval 3,3.4]. At each iteration give the maximum true error of the estimate of the root, as well as the absolute value of the approximate percent relative error (c) How many iterations would be required in part (b) to ensure that the true error is less than 10-15? (d) Verify your anser in (c) using MATLAB
