" 13.Write the value of "cosec^(2)theta-cot^(2)theta" ."

cosec^(2)theta-cot^(2)theta-1

cosec^(2)theta=1+cot^(2)theta

Write the value of 3 cot^(2)theta - 3 "cosec"^(2)theta.

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

If tan theta =(1)/(sqrt(5)), " write the value of " (("cosec"^(2)theta-sec^(2)theta))/(("cosec"^(2)theta+sec^(2)theta)).

sqrt(cosec^(2)theta-cot^(2)theta) is:

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

cosec^2 theta - cot^2 theta = 1 +…..

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

Solve cosec^(2)theta-cot^(2) theta=cos theta .
