COS X = 1 - - - - +- Problem Three: The Maclaurin series expansion for cos x is x x4 xo x8 2!*4! 6'8! Starting with the simplest version, cos x = 1, terms are added one at a time to estimate, e.g. cos ). After each new term is added, the true, &l, and approximate percent relative & 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 al Test your function using the calls: mycos(pi/4) and mycos(pi/4,4)
