`( cosec2theta - cot2theta )` -এর মান হয়—

(cosec theta - cot theta) =…………

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

cosec^2 theta - cot^2 theta = 1 +…..

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

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

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

Prove each of the following identities : (i) ("cosec"theta + cot theta )/("cosec"theta - cot theta ) = ("cosec" theta + cot theta)^(2) = 1+2cot^(2) theta + 2"cosec" theta cot theta (ii) (sec theta + tan theta ) /( sec theta - tan theta) =(sec theta + tan theta )^(2) = 1+ 2tan^(2) theta + 2 sec theta tan theta

Prove that: ("cosec" theta + cot theta)/("cosec" theta - cot theta) = ("cosec" theta + cot theta )^(2) = 1 + 2 cot^(2) theta + 2 "cosec" theta cot theta .

If (cosec theta - cot theta)=2 , the (cosec theta +cot theta) is equal to

If "cosec" theta + cot theta = -3//2 , then " cosec " theta =
