Answer 1

Answer:

plz check your question....

Step-by-step explanation:

11 sin 0 (1+cos 0) = 2 cosec (1+ cos0) sin 0 cotA

LHS

= 11 sin 0 (1+ cos 0)

= 11 sin 0 . 2 cos^2 0/2

= 11*1/cosec 0 . 2 cos^2 0/2

= cosec 0 /11 . 2 cos ^2 0/2

= 2 cosec 0 (1/11. cos^2 0/2)

= 2 cosec 0 { 1/11. (1- sin^2 0/2)}

= 2 cosec 0 { 1/11. (1- sin 0/2 * sin 0/2)}
