Use Matlab

PROBLEM STATEMENT: PART ONE 1. Consider the signal x [n] = 4 cos(in) + 6 sin(Ton). Represent, but do not print out, this signal using a list of time values and a list of signal values from n= -240 to n=240. Call the list of time values n and the list of signal values x. (a) Let xmax denote the maximum value of this signal and let nmax be the time value(s) where this maximum occurs. Let xmin denote the minimum value of this signal and let nmin be the time value(s) where this minimum occurs. Use MATLAB to determine and print out these values, including the names of the variables. (b) Let nzero denote the time value(s) where x[n] is closest to zero. Use MATLAB to determine and print out these time values, including the name of the variable. Hint: x[n] is closest to zero at the time values where x2[n] is minimum. Remember to use Publish
