I'm stuck!
Can someone please help?
I need to verify?
tanx + cotx = 2tanx - cscx secx
and
(csc(squared)x ) (cos(squared)x) - cos(squared)x = -1
Any help is greatly appreciated Thanks

Table of Trigonometric Identities
Hope that helps at all.
Recheck. Neither of those identities is valid.
#1:
#2 is not true. Recheck and make sure you typed it correctly.

They way you worked out #1. My teacher said that we should pick one side and try to manipulate it so it it equals the other side.
so your
secX cscX does not = 2tanX - cscX secX
or am I missing something?
If the identity were valid, you could plug in something and get the same answer from both
sides. It would appear the 2tan(x) is extraneous. It works out to be just
csc(x)sec(x).
Here is a valid identity.
