4.cos x^(3)

IfI=int(sin2x)/((3+4cos x)^(3))dx, then Iequals (a) (3cos x+8)/((3+4cos x)^(2))+C(b)(3+8cos x)/(16(3+4cos x)^(2))+C(c)(3cos x)/((3+4cos x)^(2))+C (d) (3-8cos x)/(16(3+4cos x)^(2))+C

Show that cos 3 x=4 cos ^(3)x-3 cos x

cos (x^(3).e^(x))

Find the derivative of cos (x^3)

Prove that: cos3x=4cos^(3)x-3cosx

Prove : cos3x=4cos^(3)x-3cosx

If (sin^(3)"" (x)/(2)-cos^(3)""(x)/(2))/(2 + sin x) = (cos x)/( 3) then x =

Prove that cos ^(3) (x-(2pi)/(3)) + cos ^(3) x + cos ^(3) (x + (2pi)/(3)) = (3)/(4) cos 3x.

Solve (sin^(3)(x)/(2)-cos^(3)(x)/(2))/(2+sin x)=(cos x)/(3)
