सिद्ध कीजिए कि : ` (1 - cos theta )/(sin theta) + (sin theta )/(1 - cos theta) = 2 "cosec" theta `

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

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

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

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

Prove that : (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

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

(cosec theta -sin theta ) (sec theta - cos theta ) (tan theta + cot theta ) = 1.

( sin theta + " cosec " theta )^(2) + ( cos theta + sec theta )^(2)=
