Question

please help me prove this identity im stuck not geting it out at all!
(1+tanx+cotx)(cosx-sinx)=(cscx/sec^2x  -secx/csc^2x)

anonymous · Answer

$$(1+tanx+cotx)(cosx-sinx) = \frac{ cscx }{ \sec^{2}x }-\frac{ secx }{ \csc^{2}x }$$
Is this correct?

Loser had the right idea posted, which he deleted for some reason. You can expand the left hand side and it will almost immediately lead you to your solution.
