/* There is a mistake in the question ( RHS part ) ,

please check it */

 LHS = cosec^{4} A - cosec^{2}A

 = cosec^{2} A ( cosec^{2} A - 1 )

 = ( 1 + cot^{2} A )\times cot^{2} A

/* By Trigonometric Identity */

 \boxed{ \pink{ 1 + cot^{2} x = cosec^{2} x }}

 = cot^{2} A + cot^{4} A

 = cot^{4} A + cot^{2} A

 = RHS
