Question 596068: verify the identity algebraically,
cos x/sin x +1 minus cos x/sin x-1 =2sec x
these problems just make no sense at all Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! verify the identity algebraically,
cos x/sin x +1 minus cos x/sin x-1 =2sec x
these problems just make no sense at all

And those problems about people's ages do?
Don't people know how old they are?
====================
The idea is to prove that the statement is true, or to disprove it.

I think you mean:
cos x/(sin x +1) - cos x/(sin x-1) =2sec x
Get rid of fractions
cos*(sin - 1) - cos*(sin + 1) = 2sec
cos*sin - cos - cos*sin - cos = 2sec
-2cos = 2sec
That's not true, not an identity.
