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

- 2 e^{- 2 x} sin (2 x) + 2 e^{- 2 x} cos (2 x)

Solution steps

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

Apply the Product Rule:

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

f = e^{- 2 x}, g = sin (2 x)

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

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

\frac{d}{d x} (sin (2 x)) = cos (2 x) \cdot 2

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

Simplify

= - 2 e^{- 2 x} sin (2 x) + 2 e^{- 2 x} cos (2 x)
