Simplify `(1-costheta)/(1+costheta)`

Simplify (1-costheta)/sintheta

Simplify (1-costheta)/sintheta

(1+costheta)/(sintheta)=?

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

Simplify: cos theta[{:(costheta,sintheta),(-sintheta,costheta):}]+sintheta[{:(sin theta ,-costheta),(costheta, sintheta):}]

solve the following expression sqrt((1-costheta)/(1+costheta))+sqrt((1+costheta)/(1-costheta)) :

Prove that- (1-costheta)/(1+costheta)=(1/(cosectheta+cottheta))^2

Prove that : (1-costheta)/(1+costheta)=(cottheta-cosectheta)^(2)

Prove that- (1-costheta)/(1+costheta)=(cosectheta-cottheta)^2

If sintheta=(7)/(25) ,then find the value of sqrt((-1costheta)/(1+costheta)) .
