Evaluate :

`Sin^3( theta )   Cos^3(theta )`

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

The value of (sin^3 theta + cos^3 theta)/(sin theta+ costheta)+((cos^3 theta - sin^3 theta))/(cos theta - sin theta) is

If 2 cos theta = sqrt(3) evaluate 3 sin theta - 4 sin^(3) theta

Evaluate sin^2 theta - cos^2 theta , if sqrt3 tan theta = 3 sin theta , theta = 0 and theta is an acute angle.

Evaluate the value of   2 tan^2 theta + cos^2 theta - 2   , where theta is an acute angle and sin theta = cos theta .

If 4 tan theta =3 , evaluate ((4 sin theta - 2cos theta +3)/(4 sin theta +2 cos theta -5))

If (sin theta + cos theta)/(sin theta - cos theta)=3 , then the value of sin^(4)theta - cos^(4)theta is:

Evaluate sin^2 theta- cos^2 theta. " If " sqrt3 tan theta = 3 sin theta, theta ne 0 and theta is an acute angle.
