derivative of

3 sin (4 x)

12 cos (4 x)

Solution steps

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

Take the constant out:

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

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

Apply the chain rule:

cos (4 x) \frac{d}{d x} (4 x)

= cos (4 x) \frac{d}{d x} (4 x)

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

= 3 cos (4 x) \cdot 4

Simplify

= 12 cos (4 x)
