Bisection Method and Accuracy of Rootfinding Consider the function f(0) = 3 cos 2r cos 4-2 cos Garcos 3r - 6 cos 2r sin 2r-5.03r +5/2. This function has exactly one root in the interval <I<1. Your assignment is to find this root accurately to 10 decimal places, if possible. Use MATLAB, which does all calculations in double precision, equivalent to about 16 decimal digits. You should use the Bisection Method as described below to...
