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

Prove the following identity : (sin theta)/(1+cos theta)+ (sin theta)/(1-cos theta)= 2/(sin theta) .

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

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

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

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

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