Answer:
Hey !!!
From LHS
cosecA / (cosecA - 1 ) + cosecA / ( cosecA + 1 )
cosecA ( cosecA - 1 ) + cosecA ( cosecA + 1 )
-----------------------------------------------
(cosecA - 1 ) ( cosecA + 1 )
cosec²A - cosecA + cosec²A + cosecA
------------------------------------------------------
cosec²A - 1
2 cosec²A / cot²A
2 / sin²A
--------------
cos²A / sin²A
2 / cos²A
= 2sec²A RHS = LHS prooved
