[" Show that: "],[qquad cot^(2)theta((sec theta-1)/(1+sin theta))+sec^(2)theta((sin theta-1)/(1+sec theta))=0]

Prove the following identity : cot^2 theta ((sec theta-1)/(1+sin theta))+ sec^2 theta ((sin theta-1)/(1+sec theta)) =0 .

What will be the value of following identities : (cot^(2) theta (sec theta -1))/((1+ sin theta))+ (sec^(2)theta (sintheta -1))/((1+ sec theta))

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

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

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

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

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

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

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