Use bisection method, newton raphson method, and secant method. Will leave rating, thank you.

4. Consider function f(x) = cos(x) 3x. Apply each method above to find all roots of f(x). For each method, print out a table that shows the progress of the method. Then use the built-in function to solve f(x) = 0 exactly and compare the true value with the approximating values of each method
