If `sintheta-costheta=0`, then `sin^3theta+cos^3theta=?`

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

If sintheta+costheta=a then find sin^4theta+cos^4theta

If sintheta-costheta=1 , then the value of sin^3theta-cos^3theta is __________ .

Sintheta - costheta = 0 Show : Sin^4theta + cos^4theta = 1/2

Solve the following trigonometric equations,(i) sin mtheta+"sin" theta=0 (ii) cos m theta-cos ntheta=0 (iii) "sin" 2theta+costheta=0 (iv) "sin"3theta+cos2theta=0

If sintheta + cos theta =1 , then the value of sintheta - costheta is:

If tantheta=1 , then the value of (8sintheta+5cos theta)/(sin^(3)theta-2cos^(3)theta+7costheta) is

costheta-cos2theta=sin3theta

If 3costheta=5sintheta , then ((5sintheta-2sec^(3)theta+2costheta)/(5sintheta+2sec^(3)theta-2costheta))=?

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