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
