derivative of

4 sin (3 x)

12 cos (3 x)

Solution steps

\frac{d}{d x} (4 sin (3 x))

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= 4 \frac{d}{d x} (sin (3 x))

Apply the chain rule:

cos (3 x) \frac{d}{d x} (3 x)

= cos (3 x) \frac{d}{d x} (3 x)

\frac{d}{d x} (3 x) = 3

= 4 cos (3 x) \cdot 3

Simplify

= 12 cos (3 x)
