Hey......!!! here is ur answer......
We have to prove that....
cosecA(1+cosA)(cosecA–cotA) = 1
On taking LHS
cosecA(1+cosA)(cosecA–cotA)
=> cosecA(1+cosA)(1/sinA–cosA/sinA)
=> cosecA(1+cosA)(1–cosA)/sinA
=> cosecA/sinA(1+cosA)(1–cosA)
=> 1/sin²A (1–cos²A)
{ Because cosecA = 1/sinA and a²–b²=(a+b)(a–b) }
=> sin²A/sin²A
=> 1 = R.H.S. { Because 1–cos²A = sin²A }
I hope it will help you......✌️✌️✌️
