Verify which of the following are trigonometric identities. 1) 1 + cos² θ / [cot²θ (1-sin²θ)]= 12 sec² θ 2) 18 cos θ[(1/ cos θ)-(cotθ/cscθ)]=18 sin² θ Both the equations are identities. Only the second equation is an identity. Only the first equation is an identity. None of the equations are identities.
