`(sin theta)/(1 + cos theta) + (1 + cos theta)/(sin theta) = 2 cosec theta`

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

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

Prove each of the following identities : (sin theta)/((1+ cos theta)) + ((1+ cos theta))/(sin theta) = 2 "cosec" theta

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

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

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

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

Prove that cos^2 theta cosec theta+sin theta=cosec theta
