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

- 16 sin (4 x)

Solution steps

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

Take the constant out:

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

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

Apply the chain rule:

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

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

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

= 4 (- sin (4 x) \cdot 4)

Simplify

= - 16 sin (4 x)

n = 1 \sum \infty \frac{2 n ^{2}}{n !}

\frac{\partial}{\partial x} (sin (π (5 x - 3 y)))

\int 1 + (\frac{4}{3 x ^{\frac{1}{3}}})^{2} d x

y = \frac{f ( x )}{x ^{2} + 2}

\frac{\partial}{\partial L} (L^{\frac{1}{4}})
