Answer:
here,
cosec theta /1 -cos²theta
= cosec theta -cos²theta
= 1/ sin theta - cos²theta
= 1-sincos² theta / sin theta
= sin² theta + cos² theta - sincos² theta / sin theta
= sin² theta + cos² theta ( 1- sin theta )/sin theta
= 1-cos²theta + cos² thrta (1-sin theta) / sin theta
= sin theta / sin theta
= 1
