" (a) "(1-cos theta)/(sin theta)=(sin theta)/(1+cos theta)

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

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

Prove the following identity : (1-cos theta)/(sin theta)= (sin theta)/(1+cos theta) .

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

Show that (1 + cos theta)/(sin theta)+ (sin theta)/(1 + cos theta) = 2 cosec theta .

(sin theta)/(1+cos theta) is equal to (1+cos theta)/(sin theta)(b)(1-cos theta)/(cos theta)(c)(1-cos theta)/(sin theta) (d) (1-sin theta)/(cos theta)

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

Prove that (1+cos theta)/(sin theta)=(1+sin theta+cos theta)/(1+sin theta-cos theta) .

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