Simplify `(asintheta)/[a(1+costheta)]`

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

Simplify (sintheta+sectheta)^(2)+(costheta+cosectheta)^(2) .

The value of (sintheta)/(1+costheta)+(sintheta)/(1-costheta) is :

(1+costheta)/(sintheta)=?

Simplify (1-costheta)/sintheta

Simplify (1-costheta)/sintheta

Simplify costheta[costhetasinthetasinthetacostheta]+sintheta[sintheta-costhetacosthetasintheta]

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

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

Simplify : 1/( Costheta Sintheta ) + ( Costheta Sintheta )/( CosthetaSintheta )
