Which statements are true about the functions y
sin(x), y = cos(x), and y
tan(x)?
Both y = sin(x) and y tan(x) are increasing on the interval (0, 2). and y cos(a) is
decreasing on that interval.
The amplitudes of y = sin(x). y cos(x) and y tan(t) are 1.
The graphs of y = sin(I) and y cos(x) do not have midlines.
The domains of y = sin(x), y cos(x), and y = tan(a) are all real numbers.
The periods of y = sin(x) and y cos(x) are 27. and the period of y = tan(s) is er
