matlab:Chapra , ROOTS [ Bracketing Method] Help needed.
If I had to find a zero of a simple function, say, x^23, using bisection, this is what I would write.

Thanx a lot.
2 questions: Q1) How do i input the equation ? Wherever it says "y = x^23" i replace it with the equation in the problem ? Q2) how do i get an error<0.00005

(1) Use a centered difference approximation O(h2) to estimate the second derivative of the function .
(a) Perform the evaluation at x = 2 using step sizes of h = 0.2 and 0.1. Compare your estimates with the true value of the second derivative. Interpret your results on the basis of the remainder term of the Taylor series expansion. (b) Write a Matlab program that evaluates the second derivative of the function (using a centered difference approximation O(h2)) on the interval [4 , 4] with a step sizes of h = 0.2 and 0.1. Plot the second derivative of the function obtained by the centered difference method along with a graph obtained from a theoretical calculation. Submit the solution of part (a) as a hard copy. For part (b), submit a fully functional program to the blackboard, and submit a copy of the program and accompanying figures as a hardcopy.
