\frac{d}{d x} (x \cdot e^{- 2 x})

e^{- 2 x} - 2 e^{- 2 x} x

Solution steps

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

Apply the Product Rule:

(f \cdot g)^{'} = f^{'} \cdot g + f \cdot g^{'}

f = x, g = e^{- 2 x}

= \frac{d x}{d x} e^{- 2 x} + \frac{d}{d x} (e^{- 2 x}) x

\frac{d x}{d x} = 1

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

= 1 \cdot e^{- 2 x} + (- 2 e^{- 2 x}) x

Simplify

= e^{- 2 x} - 2 e^{- 2 x} x

\frac{d}{d x} (\frac{x}{( ∣ y ∣ - ∣ z ∣ )})

\int \frac{x ^{4} + x ^{2} + 1}{x - 1} d x

\frac{d}{d x} (sin (x) - 3 cos (x))

\int \frac{12}{1 + t ^{2}} d t

- 5 sin (4 t)
