(tan w + 1/sec w) = sin w + cos w

Question

Verify the Identity

Answer 1

I agree with your other responder.  1/sec w = cos w

 

Therefore, making that substitution, you have tan + cos = sin + cos,

which would simplify to tan = sin, a false statement in general

Answer 2

I believe the identity is wrong. you can check by putting w=30
