- Cos2 theta / Sin 2 thetha – Cosecthetha + Sin thetha = 0
- 1/1+Sin A + 1/1-Sin thetha =2Sec2A
- Cos2 theta / Sin 2 thetha – Cosecthetha + Sin thetha = 0
- 1/1+Sin A + 1/1-Sin thetha =2Sec2A

Hint: For 1. simply take the LCM and use the general identities. Its easy to get 0.
For 2. Again take the LCM and try to use (a+b)(a-b) = (a2 – b2). Thanks.
