" (ii) "(1)/(cos theta)-(1)/(sec theta+tan theta)=(1)/(sec theta-tan theta)-(1)/(cos theta)

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

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

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

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

(1-cos^2theta)sec^2 theta= tan^2 theta

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

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

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))

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

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