`2 sec^(2) theta - sec^(4) theta - 2 "cosec"^(2) theta + " cosec"^(4) 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 =

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

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

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

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

"cosec"^(2) theta * cot^(2) theta -sec^(2) theta * tan^(2) theta - (cot^(2) theta - tan^(2) theta ) (sec^(2) theta * "cosec"^(2) theta -1)=

Prove the following: sec^2 theta + cosec^2 theta = sec^2 theta xx cosec^2 theta

If tan theta = 1/sqrt7 " then" ((cosec^(2) theta -sec^(2) theta))/((cosec^(2)theta + sec^(2) theta)) is equal to
