Question

Please solve it correctly with explanation ​

Answer 1

Answer:

1. (1/ sin theta+ 1/tan theta)^2
2. (1/sin theta +1/sin theta /cos theta )^2 [reason:tan theta = sin theta / cos theta]
3. (1/ sin theta + cos theta / sin theta)^2
4. (1+cos theta)^2/sin^2
5. (1+cos theta)^2/1-cos^2 theta. [reason: sin^2+cos^2 theta =1]
6. (1+cos theta)(1+ cos theta)/1+ cos theta)(1- cos theta) [reason:by using identity a^2-b^2=(a+b)(a-b)]
7. 1+ cos theta /1- cos theta

Hence proved
