derivative of

cos (4 - 9 x^{2})

18 x sin (4 - 9 x^{2})

Solution steps

\frac{d}{d x} (cos (4 - 9 x^{2}))

Apply the chain rule:

- sin (4 - 9 x^{2}) \frac{d}{d x} (4 - 9 x^{2})

= - sin (4 - 9 x^{2}) \frac{d}{d x} (4 - 9 x^{2})

\frac{d}{d x} (4 - 9 x^{2}) = - 18 x

= - sin (4 - 9 x^{2}) (- 18 x)

Simplify

= 18 x sin (4 - 9 x^{2})
