1.	Prove the following trigonometric identities.(i) cos A cosec A-sin A sec Acos A+sin A=cosec A-sec A(ii) sin Asec A+tan A-1+cos Acosec A+cot A-1=1
Answer» Prove the following trigonometric identities. (i) $\frac{\cos A cosec A - \sin A \sec A}{\cos A + \sin A} = cosec A - \sec A$ (ii) $\frac{\sin A}{\sec A + \tan A - 1} + \frac{\cos A}{cosec A + \cot A - 1} = 1$
