(1)/(1+sin theta)+(1)/(1-sin theta)=2sec^(2)theta

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

(1-sin^(2)theta)sec^(2)theta=1

Prove each of the following identities : (1)/((1+ sin theta)) + (1)/((1- sin theta)) = 2 sec^(2) theta

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

sqrt((1+sin theta)/(1-sin theta))+sqrt((1-sin theta)/(1+sin theta))=2sec theta

Prove :(cos theta)/(1+sin theta)+(cos theta)/(1-sin theta)=2sec theta

The trigonometric expression: cot^(2)[(sec theta-1)/(1+sin theta)]+sec^(2)theta[(sin theta-1)/(1+sec theta)] has the value has the

(8) (1+sin theta)/(1-sin theta)=(sec theta+tan theta)^(2)

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

If 1/(1-sin theta)+1/(1+sin theta)= 4 Sec theta, 0^@ यदि 1/(1-sin theta)+1/(1+sin theta)= 4 Sec theta ,है और 0^@< theta< 90^@ ,है, तो (3 Cot theta+Cosec theta) का मान क्या होगा ?
