derivative of

4 cos (x)

- 4 sin (x)

Solution steps

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

Take the constant out:

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

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

Apply the common derivative:

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

= 4 (- sin (x))

Simplify

= - 4 sin (x)

\frac{\partial}{\partial x} (y - 2 ln ∣ y ∣ + x y)

\int x \cdot e^{- 2 x^{2}} d x

\frac{d}{d x} (a x + b)

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

y^{^{'''}} - 2 y^{^{''}} - 4 y^{^{'}} + 8 y = 6 x e^{2 x}
