सिद्ध कीजिए कि:
`(1)/(sectheta-1)-(1)/(sec theta+1)=2cot^(2)theta.`

sqrt(sec^2theta-1)/(sectheta)

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

Find sec^2 theta - 1/(cot^2 theta) . .

Prove: ((1+cot^2theta)tantheta)/(sec^2theta)=cottheta

If 1/(cosec theta-1)+1/(cosec theta+1) =2 sec theta, 0^@ यदि 1/(cosec theta-1)+1/(cosec theta+1) =2 sec theta, 0^@< theta < 90^@ , है, तो (cot theta+cos theta) का मान क्या होगा ?

Prove that : sqrt((sectheta-1)/(sectheta+1))+sqrt((sectheta+1)/(sec theta-1))=2"cosec"theta

Prove that: sqrt((sectheta -1)/(sec theta +1)) + sqrt((sec theta +1)/(sec theta -1)) = "2cosec" theta

Prove the following trigonometric identities: cos^(2)theta+(1)/(1+cot^(2)theta)=1 (ii) (1)/(1+sin theta)+(1)/(1-sin theta)=2sec^(2)theta

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

Find the value of (sec^(2)theta-1).cot^(2)theta
