Prove that : (cosec theta)/(cosec theta-1)+ (cosec theta)/ (cosec theta+1)= 2 sec^2 theta .

Prove that: ("cosec"theta)/("cosec"theta-1)+("cosec"theta)/("cosec"theta+1)=2sec^(2)theta

Prove that (cot^(2)theta)/(cosec theta+1)=cosec theta-1

(cot theta)/((cosec theta+1))+((cosec theta+1))/(cot theta)=2sec theta
