Trigonometric Differentiation

G(x) = (4-cos3x)/(x^2)

Could you please include steps so that I may learn to do it myself? Thanks.

Solution Preview

What I see here is G(x)= 4-cos3x/x^2, but I suspect that x^2 is also the denom if 4 i.e. G(x)= (4-cos3x)/x^2. Therefore, I explain them both:
First consider:
G(x)= 4-cos3x/x^2
The derivitive of the first term ...
