Does
CSC([tex]\pi[/tex]/2 - x) = SinX OR 1 / SinX?

What about
CSC2([tex]\pi[/tex]/2 -x)?

Does
COT([tex]\pi[/tex]/2 + x) = -TanX or 1/-TanX?

It does NOT. HelloMotto, don't you have some kind of opinion on a multiple choice question like this? You could at least substitute some values in for x.

Whoops, I meant csc(pi/2 - x) = secx
It was a mistake on my behalf.

Now I'll believe that one. It's all up to HelloMotto now.
