derivative of

cos (4 t)

- sin (4 t) \cdot 4

Solution steps

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

Apply the chain rule:

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

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

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

= - sin (4 t) \cdot 4

\frac{\partial}{\partial x} (e^{- y} (x + e^{y}))

y = x^{2}, y = 2

3 x^{2} y^{^{'}} = y^{^{'}} + 6 x e^{- y}

(e^{4 x^{2}})^{7}

\frac{d x}{d t} = 5 x - 3
