Verify the identities. 1 − (cos x)2 (sec x)2 = (tan x)2 ; 1 − (cos x)2 (sec x)2?
please tell me the formula if you can. I just want to know how to verity it
Update:1 − (cos x)^2(sec x)^2 = (tan x)^2 therefore
1 − (cos x)^2(sec x)^2 is equal to ------ /cosx^2

what do u mean by that!
1 − (cos x)2 (sec x)2=0 As cosx.secx=1
1 â (cos x)2 (sec x)2 = (tan x)2 , is it the single identity ? if it is so , then the identity is wrong
as cos²x sec²x = cos²x * (1/cos²x) = 1 . then the left hand side becomes 0
the last one is not clear
