[" 14."sin^(3)x cos^(3)x],[" 16."sin4x sin8x]

What is the value of (sin^(3) x + cos^(3) x)/( sin x + cos x) + sin x cos x ?

If sin^(3)x cos3x+cos^(3)x sin3x=(3)/(8), then the value of 8sin4x is _(-)

If sin^(3) x cos 3x + cos^(3) x sin 3x = 3//8 , then the value of 8 sin 4x is ____________.

If sin^(3)x cos3x+cos^(3)x sin 3x=3//8 , then the value of sin 4x is ___________

If sin^(3)x cos3x+cos^(3)x sin 3x=3//8 , then the value of sin 4x is ___________

If sin^(3)x cos3x+cos^(3)x sin3x=(3)/(8), then the value of sin4x is (1)/(2)(b)1(c)-(1)/(2)(d)0

Prove that: cos^(2)2x-cos^(2)6x=sin4x sin8x

If int sin^4 x cos^4 x dx=1/128 [ax-sin4x+1/8 sin8x]+c then a=

2cosx-cos3x-cos5x= ............... A) 16 cos ^(3) x sin ^(2) x B) 16 sin^(2) x cos ^(2) x C) 4 cos ^(2) x sin ^(2) x D) 4 sin ^(2) x cos ^(2)x

sin4x=4sin x cos^(3)x-4cos x sin^(3)x
