Select all the correct answers. Which statements are true about the functions y =
sin(x), y = cos(x), and y =
tan(*);
Both y
=
sin() and y = tan(s) are increasing on the interval (0, ). and y = cos(x) is
decreasing on that interval.
The domains of y = sin(), y cos(x), and y = tan(s) are all real numbers.
The periods of y = sin(*) and y = cos(s) are 21, and the period of y = tan() is .
o The graphs of y = sin(x) and y cos(x) do not have midlines.
The amplitudes of y sin(x), y = cos(x), and y = tan(s) are 1.
