Question

please answer this.​

Answer 1

Answer:

Step-by-step explanation:

Answer 2

cross multiply :

cot2 theta + (cosec theta + 1)2/ cot theta ( cosec theta + 1)

cot2 theta + cosec2 theta + 1 + 2cosec theta  / cot theta (cosec theta +1)

(1+ cot2 theta = cosec2 theta)

cosec2 theta + cosec2 theta + 2 cosec theta/ cot theta ( cosec theta + 1)

2cosec2theta + 2 cosec theta/cot theta ( cosec theta +1)

2 cosec theta( cosec theta + 1)/ cot theta (cosec theta +1)

(Cosec theta + 1 gets cancelled)

2 cosec theta/ cot theta

2 * 1/sin theta / cos theta/sin theta

2* 1/cos theta = 2 sec theta.
