सिद्ध करें कि `(cot theta)/(1+ tan theta) = (cot theta - 1)/(2-sec^(2) theta)`

Prove that (tan^(3) theta)/(1 + tan^(2) theta) + (cot^(3) theta)/(1+ cot^(2) theta) = sec theta cosec theta - 2 sin theta cos theta

If cot theta - tan theta = sec theta , then theta=

If cot theta-tan theta=sec theta then theta=

( 1 + tan theta + sec theta ) ( 1 + cot theta - cosec theta ) =

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

Prove that (1+ cot theta + tan theta ) ( sin theta - cos theta) = (sec theta )/(cosec^(2) theta) - (cosec theta)/(sec^(2)theta) .

(tan theta)/(sec theta-1)-(sin theta)/(1+cos theta)=2cot theta

If cot theta - tan theta = sec theta , then theta =

( tan^(3) theta )/( 1+ tan^(2) theta )+ ( cot^(3) theta )/( 1+ cot^(2) theta )=
