derivative of

f (x) = 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))

\int_{- 6}^{x} 36 - t^{2} d t

(1 + x)^{\frac{1}{2}}, 0

y^{^{'}} = (y + 5) (x + 2), y (0) = - 1

h \to 0 lim (\frac{1 - ( z + h ) \cdot 2 ( z + h ) - 1 - z \cdot 2 z ^{- 1}}{h})

\int \frac{3 x ^{2} + 6}{x ^{3} + 6 x} d x
