" 15."(cos^(2)theta)/(sin theta)+sin theta=cosec theta

(cos^(2)theta)/(sin theta)-cosec theta+sin theta=0

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

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

Prove that : (1-sin theta cos theta)/ (cos theta (sec theta - cosec theta)) times (sin^2 theta - cos^2 theta)/(sin^3 theta + cos^3 theta) = sin theta

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

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

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

Prove that (cosec theta-cot theta)^(2)=(1-cos theta)/(1+cos theta) OR If sin theta+cos theta = sqrt(2) sin (90-theta) determine cot theta

sin(pi+theta)sin(pi-theta)cosec^2theta=
