cos x = 1 - 7+ 4- 6 8 ! Starting with the simplest version, cos x = 1, terms are added one at a time to estimate, c.g. cos ). After each new term is added, the true, sl, and approximate percent relatives errors can be evaluated. The MATLAB function, cos(pi/4), may be used to determine the true value. (cos x) True = Write a MATLAB function, mycos, that estimates cos x as outlined above. . The first line in the function is: function out1 = mycos(ang.n) where, ang is the angle, e.g. pi/4, and n is the number of significant figures. Number of significant figures, n, is an optional input. If it is not provided by the user, set n = 5. Design the output of the function similar to the following format: Iteration Outl e t sal Test your function using the calls: mycos(pi/4) and mycos(pi/4,4)
