(sin theta/cot theta+cosec theta) - (sin theta/cot theta-cosec theta =2 [we have to prove this]
LHS= Sin theta[1/cot theta+cosec theta - 1/cot theta-cosec theta]
sin theta[cot theta -cosec theta - cot theta -cosec theta/ (cot theta+cosec theta) (cot theta- cosec theta)]
cutting cot theta
sin theta[-2 cosec theta /cot^2 theta - cosec^2 theta]
sin theta(-2 cosec theta/-1)
(using indentity= 1+cot^2 theta= cosec^2 theta)
sin theta × 2 × 1/ sin theta =2
R.H.S =2
hence proved
