\frac{d}{d x} (cos (4 x^{3}))

- sin (4 x^{3}) \cdot 12 x^{2}

Solution steps

\frac{d}{d x} (cos (4 x^{3}))

Apply the chain rule:

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

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

\frac{d}{d x} (4 x^{3}) = 12 x^{2}

= - sin (4 x^{3}) \cdot 12 x^{2}

y^{^{'}} + \frac{y}{2 + 3 t} = 3

\int \frac{e ^{2 x}}{e ^{x} + e ^{- x}} d x

\int (x^{2} - 1) sin (2 x) d x

\frac{d}{d m} (im)

y = \frac{15}{ln ( x )}
