Evaluate for `theta`
`( Sintheta + Costheta ) ( 1 - Sintheta . Costheta ) = Sin^3theta `

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

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

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

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

Evaluate : a Sin^3theta Costheta + a Sintheta Cos^3theta

Evaluate : ( Cos^2theta - Sin^2theta ) / ( ( Costheta - Sintheta )^2

Evaluate : ( Cos^2theta - Sin^2theta ) / ( ( Costheta - Sintheta )^2

If sintheta - costheta = 0 , then sin^4theta - cos^4theta = ?

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

If sintheta+costheta=1 , then Find sintheta.costheta
