cosec theta =1÷sin theta
cosec theta÷cosec theta-1+cosec theta÷cosec theta+1(question)
1/sin theta÷1/sin theta-1+1/sin theta÷1/sin theta+1
taking L.C.M
1/sin theta÷1-sin theta/sin theta+1/sin theta÷1+sin theta/sin
when doing division we have to take reciprocal and multiply
1/sin theta×sin theta/1-sin theta+1/sin theta×sin theta/1+sin theta
sin theta gets cancel in the tow terms
1/1-sin theta+1/1+sin theta
1+sin theta×1-sin theta/1-sin^2 theta
1-sin^2 theta/1-sin^2 theta
they both get cancelled
