Suppose that you have a problem with your calculator so that the division button has stopped working, and you have addition, subtraction, and multiplication only. Given a real number $,$ suggest a quadratically convergent iterative formula to compute $,$ correct to a user$-$specified tolerance. Write a MATLAB routine that implements your algorithm, using as a convergence criterion, and test your routine to with two different initial guesses and Discuss your results.
