sin x/ 1 + cosx + 1 + cosx/sinx = 2cosecx ( To prove)
⇒ sin²x + ( 1 + cosx)² / ( 1 + cosx ) sinx (Taking LCM)
⇒ sin²x + 1 + cos²x + 2cosx/ ( 1 + cosx) sinx (Opening the square)
⇒ 2 + 2cosx / ( 1 + cos x) sinx ( As sin²x + cos²x = 1)
⇒ 2 ( 1 + cos x) / ( 1 + cos x) sinx ( Taking 2 common out)
⇒ 2 / sinx (Cancelling the common term
of ( 1 + cos x)
⇒ 2cosec x = RHS
