Answer 1

Answer:

1 is the right answer plz mark brialint answer

Step-by-step explanation:

cosec^2x×sin^2x=1 ok

Answer 2

Answer:

1

Step-by-step explanation:

Given :

( 1  + cot² Ф ) sin² Ф

We know :

cosec² Ф = 1 + cot² Ф

Replacing value of ( 1 + cot² Ф ) by cosec² Ф

cosec² Ф × sin² Ф

We know :

cosec² Ф = 1 / sin² Ф

= > sin² Ф / sin² Ф

= > 1 .

Therefore , the value of ( 1 + cot² Ф ) is 1 .
