You can loop over values like this: for x in [-60.0, -45.0, -30.0]: # etc; notice how the .0 specifies a float print(‘D({0}) = {1}’.format(x, A*math.cos(x)**2+B*math.sin(x)+C)) If you intend for the output to be machine-readable, maybe change the format string to something like ‘{0},{1}’ for simple CSV output. Just print will print nothing (well, or … Read more
