Prove sin(y) + sin(y) cot2(y) = cosec(y)

Here is the step by step demonstrations to prove sin(y) + sin(y) cot2(y) = cosec(y) trig identity easily.


Sin(y) + sin(y) cot2(y) = cosec(y) - Trig Identities Proof

LHS
= sin(y) + sin(y) cot2(y)

= sin(y) × (1 + cot2(y))

= sin(y) × (cosec2(y))

= sin(y) ×
1

sin2(y)

=
1

sin(y)

= cosec(y)

= RHS

Hence Proved.
