Question

sin^2 A * (1 + cot^2 A) = 1​

Answer 1

Step-by-step explanation:

cosec^2A - cot^2 = 1

LHS= (1+cot^2A) sin^2

cosec ^2 ×sin^2

1/sin^2× sin^2

= 1 Answer RHS

Answer 2

identify : cosec^2 A- cot ^2:A = 1

LHS: (1+ cot^2 A) sin ^2 A

= cosec ^2 A * sin ^2 A

1/ sin ^2 A * sin ^2 A

= 1

= RHS
