Answer 1

Solve for x in the given interval.

csc(x) = -1, for 3π≤x≤4π

Answer 2

\[\csc x=\frac{1}{\sin x}\]
\[\large \frac{1}{\sin x}=-1\]
\[\large 1=-\sin x\]
\[\large \sin x=-1\]
\[\large x=\frac{3\pi}{2}, \frac{7\pi}{2}\]
Using your restriction, it would be the last answer I wrote down.
\[\large x=\frac{7\pi}{2}\]
