i'm 90% sure it's right please tell me if it's not

idk

step-by-step explanation:

maybe try   if it is work from a book, if not try

find the magnitude of the trig term  

csc

(

x

)

−

1

by taking the absolute value of the coefficient.

1

find the lower bound of the range.

2

find the upper bound of the range.

tap for more

y

=

0

the range is  

y

≤

−

or  

y

≥
