check your quesion once again
its ryt
so we need to find value of theta
sorry it must be (1+cot²Φ)(1-cosΦ)(1+cosΦ) = 1

cosec square =1+cot square phi
1+cos phi(1-cos phi)=1 -cos square phi=sin square phi
so sin square × coesc square =1
1+cos phi(1-cos phi)=1 -cos square phi=sin square phi
so sin square × coesc square =1
