`(tantheta+sectheta-1)/(tantheta-sectheta+1)`

sectheta/tantheta=?

Prove that : (sectheta+tantheta-1)/(tantheta-sectheta+1)=(costheta)/(1-sintheta)

((1+tantheta+sectheta)(1+cottheta-cosectheta))/((sectheta+tantheta)(1-sintheta)) is equal to:

(tantheta + sintheta)/(tantheta - sintheta) =(sectheta + 1 )/ (sectheta -1)

Prove that (tantheta+sintheta)/(tantheta-sintheta)=(sectheta+1)/(sectheta-1) .

Prove the following : (All angles are acute angles.) (tantheta+sintheta)/(tantheta-sintheta)=(sectheta+1)/(sectheta-1)

Prove the following trigonometric identities: (tantheta+sintheta)/(tantheta-sintheta)=(sectheta+1)/(sectheta-1)

Solve: (1 + tantheta + sectheta)(1+ cottheta - cosectheta)

(1+cottheta-cosectheta)(1+tantheta+sectheta)=?
