once again these are single valued functions so only answer that make senses is the last one

anonymous · Answer

$$cosec^{-1}\sqrt{2} = y$$
$$\sqrt2 = cosecy$$
$$y = \frac{\pi}{4}$$

anonymous · Answer

hope this is clear.  you cannot say evaluate 
$$f(\sqrt{2})$$ and then give a set of numbers.  must be one number or it isn't a function

anonymous · Answer

hold the phone

anonymous · Answer

$$\sec(\frac{\pi}{3})=\frac{1}{\sin(\frac{\pi}{3})}=\frac{2}{\sqrt{3}}$$

anonymous · Answer

so that answer is not right. you have no correct answer here.  where did the question come from?
