derivative of

5 e^{x} cos (x)

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

Solution steps

\frac{d}{d x} (5 e^{x} cos (x))

Take the constant out:

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

= 5 \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)

= 5 (\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)

= 5 (e^{x} cos (x) + (- sin (x)) e^{x})

Simplify

= 5 (e^{x} cos (x) - e^{x} sin (x))

\frac{d}{d x} (arctan (\frac{300}{x}))

h (x) = ln (x + x^{2} - 6)

\int sec^{6} (6 x) d x

\int e^{x} 4 x d x

x \to \frac{3}{5} lim (∣ - 5 x + 3 ∣)
