The domain is all real numbers - False
The domain is all reals except at (pi/2) + n* pi where n is an integer
The range is all real numbers - True
The function has an asymptote at pi/ 2 - True
The period is pi - True
There is no end behavior - False
The end behavior between the asymptotes is down to negative infinity on the left and up to positive infinity on the right
