Answer:

The following as a single sine  function of an angle:

12 sin3\theta \cos3\theta cos 6\theta =3\times \sin12\theta

Step-by-step explanation:

Given : 12 sin3\theta \cos3\theta cos 6\theta

Using identity:

Sin2x=2\times \sin x \cos x

=6\times 2\times sin3\theta \cos3\theta \cos 6\theta

=6\times (2\times sin3\theta \cos3\theta) \cos 6\theta

=6\times \sin 6\theta \cos 6\theta

=3\times (2\times \sin 6\theta \cos 6\theta)

=3\times \sin12\theta

The following as a single sine  function of an angle:

12 sin3\theta \cos3\theta cos 6\theta =3\times \sin12\theta
