Simplify :

`Sintheta/Costheta` + 1

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

Simplify (1-costheta)/sintheta

Simplify (1-costheta)/sintheta

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

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

Show that : Costheta /( 1 - Sintheta ) + Costheta /( 1 + Sintheta ) = 2/Costheta

Evaluate : ( Sintheta - Costheta )^2 + ( Sintheta + Costheta )^2 = ?

If   Costheta /( 1 - Sintheta ) + Costheta /( 1 + Sintheta ) = 4 ; then find the value of theta

If Sintheta + Costheta = 1 Sintheta - Costheta = ?

Sintheta + Costheta = 2 Sintheta - Costheta = ?
