If sin 2 theta =3/4, then sin ^(3) theta + cos ^(3) theta = ............... A) (sqrt5)/( 8) B) (sqrt7)/(8) C) (sqrt11)/(8) D) (5sqrt7)/(16)

If tan theta=(3)/(4), then (4sin^(2)theta-2cos^(2)theta)/(4sin^(2)theta+3cos^(2)theta)

If tan theta=(3)/(4), then (4sin^(2)theta-2cos^(2)theta)/(4sin^(2)theta+3cos^(2)theta)

sin4 theta-sin2 theta=cos3 theta

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

cos^(3)theta sin 3theta + sin^(3)theta cos3theta=3/4

Prove that: sin4 theta=4 sin theta cos^(3)theta-4cos theta sin^(3)theta

Taking theta=30^(@) , verify each of the following (i) sin 3theta=3sin theta -4sin^(3) theta (ii) cos3 theta=4cos^(3)theta-3cos theta

Prove each of the following identities : (cos^(3) theta + sin^(3) theta)/(cos theta + sin theta ) + (cos^(3) theta - sin^(3) theta)/(cos theta - sin theta ) = 2
