Answer:
=(1/sin 0 - cos0/sin0)
=(1-cos0/sin0) ²
=(1-cos0)2/sin20
=(1-cos0) ²/1-cos20(with identity)
=(1-cos0) ²/1²-cos20)
=(1-cos0) ²/(1-cos0) (1+cos0) { ab one plus cos20cut jaega upar square}
= 1- cos0/1+cos0
it's done

Answer: I'm using theta as A
Given that,
(CosecA-cotA)²
=(1/sinA-cosA/sinA)²
=(1-cosA/sinA)²
=(1-cosA)²/sin²A
=(1-cosA)(1-cosA)/1-cos²A
=(1-cosA)(1-cosA)/(1+cosA)(1-cosA)
=1-cosA/1+cosA
Hence proved....
