Answer 4

see if this helps http://www.themathpage.com/atrig/inverseTrig.htm#relations

Answer 5

yeah
\[1/sinx=cosecx\]
\[1/cosx=secx\]
\[1/tanx=cotx\]
those are inverses of sinx,cosx tanx

Answer 6

Okay, thanks you guys!!

Answer 7

Isn't it like a opposite like negative. \[\cos^{-1} \] \[\sin^{-1} \] etc that's what I thought but no probs.

Answer 8

yeah if u want inverse functions then
take a example like
\[x=\sin \theta\]
then\[\theta=\sin^{-1} x\]
like this

Answer 9

Oh right! I haven't don't this is a while so I forgot.

Answer 10

Oh i got it right!
