3sin3x=6sin3xcos3x
is it ture

3/4sin3A/2=3/2sin3A/4-cos3A/4
how you solved:confused:

Look at the right side.

Recognize the identity sin(2x)=2sin(x)cos(x)

You have sin(6x)=2sin(3x)cos(3x)

3sin(6x)=6sin(3x)cos(3x)

Is it true or false?

Thanks galactus you are right can you solve anther qusetion to
