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

Prove the following : (i) sec theta ( 1-sin theta ) ( sec theta + tan theta ) = 1

Prove that sec theta(1-sin theta)(sec theta+tan theta)=1

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

Prove that : sec theta (1 - sin theta ) (sec theta + tan theta ) = 1

Prove that : sec theta (1 - sin theta ) (sec theta + tan theta ) = 1

For 0 prec theta prec 90 , if (sec theta( 1- sin theta)(sec theta+tan theta))/(sec theta-tan theta)^2=(1+k)/(1-k) , then k is is equal to : 0 prec theta prec 90 के लिए , यदि (sec theta( 1- sin theta)(sec theta+tan theta))/(sec theta-tan theta)^2=(1+k)/(1-k) है, तो k का मान किसके बराबर है ?

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

Prove each of the following identities : (i) (sec theta -1)/(sec theta +1) =(sin^(2) theta)/((1+ cos theta)^(2) ) (ii) (sec theta - tan theta)/(sec theta + tan theta) = (cos^(2) theta)/((1+ sintheta)^(2))

Prove that (sec theta-tan theta+1)/(sec theta+tan theta+1)=(1-sin theta)/(costheta) .
