Prove that cos thita -sin thita+1/cos thita +-sin thita-1 =cosec thita

1.	Prove that cos thita -sin thita+1/cos thita +-sin thita-1 =cosec thita+cot thita
Answer» Cos /sin - sin /sin +1/sin %cos /sin +sin /sin - 1/sin =cot - 1+cosec /cot +1-cosec =cot +cosec - (cosec 2-cot2)/cot - cosec +1=cot +cosec - (cosec +cot) (cosec - cot) /(cot - cosec) +1=cot +cosec-(-1)/1=cot +cosec
