" 4.Prove: "(sin theta)/(1-cos theta)=cosec theta+cot theta

Prove that (Sin theta)/(1-cos theta)=cosec theta+cot theta OR Prove that (Sin theta - 2 Sin^(3) theta)/(2cos^(3)theta-cos theta)=tan theta

Prove that : (sin theta)/(1 - costheta) = cosec theta + cot theta

Prove that : (sin theta)/(1 - costheta) = cosec theta + cot theta

csc theta(1+cos theta)(csc theta-cot theta)=1

Prove that (i) (sin theta)/((1- cos theta))=("cosec" theta + cot theta) (ii) (1)/((sec theta - tan theta))=(sec theta + tan theta)

Prove that (i) (sin theta)/((1- cos theta))=("cosec" theta + cot theta) (ii) (1)/((sec theta - tan theta))=(sec theta + tan theta)

Prove that: (sin theta)/(1 - cos theta) + (tan theta)/(1 + cos theta) = cosec theta + cot theta + sec theta cosec theta - cosec theta

prove that (1-cos theta)/(1+cos theta)=(csc theta-cot theta)^(2)

Prove that:- sqrt((1+cos theta) / (1-cos theta)) = cosec theta + cot theta

Prove the following identity : sqrt ((1-cos theta)/(1+cos theta)) = cosec theta-cot theta .
