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

(cos theta)/(1+sin theta)+(1+sin theta)/(cos theta)=2sec theta

prove that (cos theta)/(1-tan theta)+(sin theta)/(1-cot theta)=cos theta+sin theta

Prove that : (cos theta)/(1-tan theta)+(sin theta)/(1-cot theta)=sin theta+cos theta

(sin 2 theta)/(sin theta)-(cos 2 theta)/(cos theta)= A) sec theta B) tan theta C)1 D)2

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

Prove that: ((1)/(cos theta)-(1)/(sin theta))(1+(sin theta)/(cos theta)+(cos theta)/(sin theta))=sec theta tan theta-cosec theta cot theta

Prove that (sin theta-cos theta+1)/(sin theta+cos theta-1)=1/(sec theta-tan theta) ,using the identity sec^2 theta=1+tan^2 theta .

(cos theta-sin theta) / (cos theta + sin theta) = sec2 theta-tan2 theta

Prove that :(cos theta-sin theta)/(cos theta+sin theta)=sec2 theta-tan2 theta

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