" If "cot theta=sqrt(7)" and "theta" does not lie in the first quadrant,then "(cosec^(2)theta-sec^(2)theta)/(cosec^(2)theta+sec^(2)theta)=

If cot theta = sqrt(7) and theta does not lie the first quadrant , then ( " cosec"^(2) theta - sec^(2) theta )/( "cosec"^(2) theta + sec^(2) theta )=

tan^(2)theta+cot^(2)theta+2=sec^(2)theta cosec^(2)theta

If tan theta=(1)/(sqrt(7)), then (csc^(2)theta-sec^(2)theta)/(csc^(2)theta+sec^(2)theta)=?

Prove : cot^(2) theta-tan^(2)theta=cosec^(2)theta-sec^(2)theta

Prove : cot^(2) theta-tan^(2)theta=cosec^(2)theta-sec^(2)theta

Prove that cosec^(2) theta + sec^(2) theta = cosec^(2) theta sec^(2) theta .

If tan theta=1/ sqrt7 , then ((cosec^2 theta-sec^2 theta)/(cosec^2 theta+sec^2 theta)) =

Prove: cot^(2)theta- tan^(2) theta=cosec^(2)theta-sec^(2)theta .

If tan theta =(1)/(sqrt(7)) and theta is an acute angle , then ("cosec"^(2) theta - sec^(2) theta )/( "cosec"^(2) theta + sec^(2) theta =

If tantheta=1/(sqrt7) , show that (cosec^(2)theta-sec^(2)theta)/(cosec^(2)theta+sec^(2)theta)=3/4
