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

(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)= _______

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

(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

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

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