Question

If x is not a whole number times π, then csc(-x) + csc(x) can be simplified as.........

Answer 1

use this :
\(\csc (-x) = -\csc x\)

Answer 2

im not sure what to do

Answer 3

since, \(\sin (-x) = -\sin x\)

and sin x = 1/csc x
we also have
\(\csc (-x) = - \csc x\)

so just replace csc (-x) in your question by - csc x and see what u get ??

Answer 4

-csc(x) =-cscx

Answer 5

csc(-x) + csc(x)

= - csc x + csc x
= 0
makes sense ?

Answer 6

oh, yes
