if `costheta=a/b` then `sintheta.cottheta+cosectheta.tantheta`

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

Solve : 3tantheta+cottheta=5 cosectheta

(sintheta+costheta)(tantheta+cottheta)=

Prove that sintheta/(1-costheta)=cosectheta+cottheta .

Prove that : sintheta(1+tantheta)+costheta(1+cottheta)=cosectheta+sectheta

Prove that : sintheta(1+tantheta)+costheta(1+cottheta)=cosectheta+sectheta

Prove the following (cosectheta-sintheta)(sectheta-costheta)=1//(tantheta+cottheta)

Prove the following costheta/(1-tantheta) +sintheta/(1-cottheta)=sintheta+costheta

Prove the following tantheta/(1-cottheta) +cottheta/(1-tantheta) =sectheta.cosectheta+1=1+tantheta+cottheta

If tantheta =3," then " (sintheta-costheta)/(sintheta+costheta) is equal to
