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 = `

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

Prove that 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 )=

Prove that 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

If tan theta = 1/(sqrt(11)) and 0 < theta < pi/2 , then the value of ("cosec^2 theta - sec^2 theta)/(cosec^2 theta + sec^2 theta) is

The value of 2 sec^(2) theta - sec^(4) theta - 2 cosec^(2)theta + cosec^(4) theta is

If tan theta=1/ sqrt7 , then ((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)) is equal to
