cosecA(1-cosA)(cosecA+cotA)=1

(coseca+sina)(coseca-sina)=cot^2a+cos^2a

cosa/coseca-1+cosa/coseca-1

(1+tan^2a)cot a/cosec^2a=tana

cota-coseca+1/(cota-coseca+1) = (1+cosa/sina)

seca(1-sina)(seca+tana)=1

sec2a+cosec2a=sec2a×cosec2a

tana/1+seca-tana/1-seca=2coseca

Sir... ques mei jab Lcm lia toh first part mei

(1+cosA)/ SinA kiyu aaya.
(1+cosA.sinA)/sinA kiyu nhi... I'm hella confused.
