Heya dear

here is ya answer

====================================

LHS

( cosecA - cotA )²

= ( 1/ sinA - cosA/sinA )²

= ( 1 - cosA/ sinA )²

= ( 1 + cosA )²/ sin²A

= ( 1 - cosA )²/ 1 - cos²A

= ( 1 - cosA ) ( 1 - cosA )/ ( 1 + cosA ) ( 1 - cosA )

= 1 - cosA / 1 + cosA

.°. RHS

thanks

Answer:

cosecA - cotA )²


= ( 1/ sinA - cosA/sinA )²


= ( 1 - cosA/ sinA )²


= ( 1 + cosA )²/ sin²A


= ( 1 - cosA )²/ 1 - cos²A


= ( 1 - cosA ) ( 1 - cosA )/ ( 1 + cosA ) ( 1 - cosA )


= 1 - cosA / 1 + cosA


.°. RHS
