The ratio Pi (pi) can be represented by the following series: pi = 3 Squareroot 3 sigma_k=0^infinity (-1)^k/(2k + 1)3^k a. Write a script Matlab file that finds an approximation for pi using the first 1000 terms, i.e, pi_approx = 2 Squareroot 3 sigma_k=0^1000 (-1)^k/(2x + 1)3^k b. Modify your code in part-a such that you stop when you have an absolute error that is less than 10^-14. The absolute error is defined as: Abserror = |pi - pi_approx| Print the number of iterations needed to get to the above absolute error
