let theta = x

cosec4x - cosec2x

(cosec2x)2 - ( 1 + cot2x)

( 1 + cot2x)2 - 1 - cot2x

1 + cot4x + 2cot2x - 1 - cot2x

cot4x + cot2x = RHS.........

Answer:

hope it helps

Step-by-step explanation:=> cosec 4 theta - cosec 4 theta = cot 2 theta

+cot 4 theta

=> 1+ cot 4 theta -1+cot 2 theta = cot 2 theta +cot 4 theta ( because :-cosec 4 theta = 1+cot 4 theta & cosec 2 theta = cot 2 theta )

=> cot 4 theta + cot 2 theta = cot 2 theta + cot 4 theta

hence proved
