Evaluate :
`Sintheta Costheta + Costheta Sintheta `

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

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

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

Sintheta + Costheta = 2 Sintheta - Costheta = ?

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

If Sintheta + Costheta = 1 Sintheta - Costheta = ?

Evaluate : 1/costheta + sintheta/costheta = ?

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

If (sintheta+costheta)/(sintheta-costheta)=3 and theta is an acute angle, then the value of (3sintheta+4costheta)/(8costheta-3sintheta) is
