Question

Evaluate arccsc2

I thought the answer was just pi/6 or 30 degrees but I see other pi/6 with other fractions. What would you chose?

Answer 1

I think it is {pi/6,5pi/6}

Answer 2

C.?

Answer 3

\(arcsc (2) = \theta\), that is \( csc(\theta) = 2\) but \(csc (\theta)= \dfrac{1}{sin (\theta)} =2\)
hence \(sin(\theta)= \dfrac{1}{2}\)
those values of \(\theta\) are \(\dfrac{\pi}{6}, \dfrac{5pi}{6}\)

Answer 4

Ok thank you for explaining that to me!
