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

If tan theta =(1)/(sqrt(7)) , find the value of ("cosec"^(2)theta-sec^(2)theta)/("cosec"^(2)theta+sec^(2)theta) .

Given tantheta=1/sqrt3 , find the value of ("cosec"^(2)theta-sec^(2)theta)/("cosec"^(2)theta+sec^(2)theta) .

Write the value of (tan^(2)theta-sec^(2)theta)/(cot^(2)theta-"cosec"^(2)theta).

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

If tantheta=sqrt((1)/(13))and theta is acute , then what is the value of ((cosec^(2)theta-sec^(2)theta))/(cosec^(2)theta+sec^(2)theta)) ?

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

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

(sec^(2)theta-sin^(2)theta)/(tan^(2)theta)=cosec^(2)theta-cos^(2)theta
