Question

Domain and Range of y=csc^-1(x)

Answer 1

or inverse cosecant

Answer 2

any clue @Pamela16

Answer 3

Hmm I am not really good at this! y = csc(x)
= 1 / sin(x)

By the no division-by-zero rule:
sin(x) ≠ 0
x ≠ nπ where n is an integer.

So the domain is
All x such that x ≠ nπ where n is an integer.

The range is all real numbers since the function goes off to infinity at the discontinuities. I am not sure if this will help you :)
