derivative of

y = 4 cos (4 x^{2})

- 32 x sin (4 x^{2})

Solution steps

\frac{d}{d x} (4 cos (4 x^{2}))

Take the constant out:

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

= 4 \frac{d}{d x} (cos (4 x^{2}))

Apply the chain rule:

- sin (4 x^{2}) \frac{d}{d x} (4 x^{2})

= - sin (4 x^{2}) \frac{d}{d x} (4 x^{2})

\frac{d}{d x} (4 x^{2}) = 8 x

= 4 (- sin (4 x^{2}) \cdot 8 x)

Simplify

= - 32 x sin (4 x^{2})
