Question

PRECALC H

For what numbers x, -2π ≤ x ≤ 2π, does the graph of csc(x) = 1? For what numbers x does csc(x) = -1? PLEASE HELP ME & EXPLAIN

Answer 1

why?

Answer 2

csc x = 1/sinx

and sin(pi/2) = 1 and sin(-pi/2) = -1

check this http://www.wolframalpha.com/input/?i=sinx

where ever you have values 1 and -1 of sinx, you have csc the same.

P.S. sorry for above wrong answer. typed whatever came to mind
