If `p=(2sin theta)/(1+cos theta+sin theta), and q=(cos theta)/(1+sin theta)`, then

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

If x=(2sin theta)/(1+cos theta+sin theta), then prove that (1-cos theta+sin theta)/(1+sin theta) is equal to x

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

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

Prove each of the following identities : (i) (1+ cos theta + sin theta)/(1+ cos theta - sin theta) =(1+ sin theta)/(cos theta) (ii) (sin theta + 1- cos theta)/(cos theta - 1 + sin theta) = (1+ sin theta)/(cos theta)

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

" 4."(sin theta)/(1+cos theta)+(1+cos theta)/(sin theta)=(2)/(sin theta)

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