The inputs to MATLAB functions sin, cos, and tan are in radians, and the output of functions asin, acos, atan, and atan2 are in radians. Create a new set of functions sin_d, cos_d, and so forth whose inputs and outputs are in degrees. Be sure to test your functions. (Note: Recent versions of MATLAB have built-in functions sind, cosd, and so forth, which work with inputs in degrees instead of radians. You can evaluate your functions and the correspond- ing built-in functions with the same input values to verify the proper operation of your functions)
