Answer 1

Answer:

LHS= (Cosec@+ 1/cot@) ²

=(cosec@-1)²/cot²@

=(cosec@-1) (cosec@+1) /cosec²@-1

=(cosec@-1) (cosec@+1) /(cosec@-1) (cosec@-1)

=cosec@+1/cosec@-1

hence LHS = RHS

Step-by-step explanation:

PLEASE note the use of @ instead of theta

formula used: a²-b² = (a-b) (a+b)

cot²@= cosec²@-1
