Find `sintheta /(1+costheta) +sintheta/(1-costheta) =?`

(1+costheta+sintheta)/(1+costheta-sintheta)=(1+sintheta)/(costheta)

(sintheta)/(1+costheta) + (1+costheta)/(sintheta) = 2 cosec theta

Prove the following identity: (costheta)/(1-sintheta)=(1+costheta+sintheta)/(1+costheta-sintheta)

Prove that : (1-costheta)/(sintheta)+(sintheta)/(1-costheta)=2"cosec "theta

The distance between the points (costheta,sintheta) and (sintheta,-costheta) is

Prove that: (i) (costheta)/(1-sintheta)=(1+sintheta)/(costheta) (ii) (1+costheta-sin^(2)theta)/(sintheta+sinthetacostheta)=cottheta (iii) 1+(tan^(2)theta)/(1+sectheta)=sectheta
