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