Find the value of `cosec^2 theta - cot^2 theta - 1`

If cosectheta-cottheta =2 , find the value of cosec^(2)theta+cot^(2)theta .

If cosec^(2)theta+cot^(2)theta=(5)/(7) , then find the value of cosec^(4)theta-cot^(4)theta .

If "cosec"theta=x+(1)/(4x) , then find the value of "cosec"theta+cot theta .

Without expanding, find the value of |(cosec^(2)theta,cot^(2)theta,1),(cot^(2)theta,cosec^(2)theta,-1),(42,40,2)|

If cot theta =80/39 , find the value of cosec theta . यदि cot theta =80/39 , तो cosec theta का मान प्राप्त कीजिए

The value of ("cosec" theta -cot theta)^(2) is

If cot theta = (40)/(9) , find the values of cosec theta and sin theta .
