Question

1+cot²A/1+ cosecA. Please help.​

Answer 1

Answer:

1 + cot^2A  + cosec A

Step-by-step explanation:

then value = cosec ^2 A + cosec A

since cosec ^A - cot ^2 A = 1

since cosec ^2 A = 1 + cot ^2 A

Answer 2

Step-by-step explanation:

1+cot²A / 1+cosecA × 1-cosec A/1-cosec A

=> (1+cot²A)(1-cosec A)/1-cosec²A

=> - (cosec²A)(1-cosec A)/cot²A

=> - (cosec²A - cosec³A)/cot²A

=> - [cosec²A/cot²A - cosec²A/cot²A × cosec A]

=> - cosec A
