Homework Help: Quick trig identity question

  1. Nov 18, 2008 #1
    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.
