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

Evaluate : ( 1 + sintheta + costheta )^2 =

Evaluate : ( ( Sin^3theta + Cos^3theta ) / ( Sintheta + Costheta ) ) + Sintheta Costheta =

Evaluate : ( Sintheta + Costheta ) ( 1 - Sintheta Costheta ) = Sin^3theta + Cos^3theta

Evaluate : ( sintheta + costheta ) ( sintheta - costheta )

Evaluate : (( 1 + sintheta ) ( 1 - sintheta )) / ( ( costheta ) ( - costheta ) )

Evaluate : 1/costheta + sintheta/costheta = ?

Evaluate : ( Cos^3theta + Sin^3theta ) / ( Costheta + Sintheta ) + ( Cos^3theta - Sin^3theta ) / ( Costheta - Sintheta )

Evaluate costheta/sintheta
