derivative of

y = 6 e^{x} cos (x)

6 (e^{x} cos (x) - e^{x} sin (x))

Solution steps

\frac{d}{d x} (6 e^{x} cos (x))

Take the constant out:

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

= 6 \frac{d}{d x} (e^{x} cos (x))

Apply the Product Rule:

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

f = e^{x}, g = cos (x)

= 6 (\frac{d}{d x} (e^{x}) cos (x) + \frac{d}{d x} (cos (x)) e^{x})

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

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

= 6 (e^{x} cos (x) + (- sin (x)) e^{x})

Simplify

= 6 (e^{x} cos (x) - e^{x} sin (x))

\int 1^{- x} d x

\int x e^{x - 1} d x

\frac{\partial}{\partial x} (y \cdot x)

x \to 6 lim (2 x + 3 x)

x \frac{d y}{d x} + y = 2 x + 1
