Question

Evaluate arccsc√2.

A. {π/3± 2πn, 5π/3± 2πn}
B. {π/4±2nπ, 3π/4± 2nπ}
C. {π/6, 5π/6}
D. π/3

Answer 1

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

Answer 2

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

Answer 3

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

Answer 4

hold the phone

Answer 5

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

Answer 6

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