1+cos theta+sin theta/1-cos theta+sin theta=cot theta/2​

Step-by-step explanation:

Giventhat,

cosθ+sinθ−1/

cosθ−sinθ+1

=cosecθ+cotθ

Now,

Divide both N and Dr with sinθ

= cosθ−sinθ+1/sinθ / cosθ+sinθ-1/sinθ

= cotθ-1+cos ecθ / cotθ+1-cos ecθ

= cotθ + cos ecθ - ( cos ec²θ - cot ec²θ ) / cotθ - cos ec θ +1

= cotθ + cos ecθ ( 1 - ( cos ec²θ - cot²θ ) / cosθ - cos ecθ + 1
