Select all the correct answers. Which statements are true about the functions y = sin(1), y = cos(x), and y = tan(x)? Both y = sin(s) and y = tan(s) are increasing on the interval (0, 3), and y = cos(r) is decreasing on that interval. The domains of y = sin(), y = cos(x) and y tan(s) are all real numbers. The amplitudes of y = sin(). y = cos(x) and y = tan(x) are 1. The graphs of y = sin(s) and y = cos(x) do not have midlines. The periods of y = sin(x) and y = cos(r) are 27, and the period of y = tan(x)
