derivative of

\frac{5 x}{x + 4}

\frac{20}{( x + 4 ) ^{2}}

Solution steps

\frac{d}{d x} (\frac{5 x}{x + 4})

Take the constant out:

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

= 5 \frac{d}{d x} (\frac{x}{x + 4})

Apply the Quotient Rule:

(\frac{f}{g})^{'} = \frac{f ^{'} \cdot g - g ^{'} \cdot f}{g ^{2}}

= 5 \cdot \frac{\frac{d x}{d x} ( x + 4 ) - \frac{d}{d x} ( x + 4 ) x}{( x + 4 ) ^{2}}

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

\frac{d}{d x} (x + 4) = 1

= 5 \cdot \frac{1 \cdot ( x + 4 ) - 1 \cdot x}{( x + 4 ) ^{2}}

Simplify

5 \cdot \frac{1 \cdot ( x + 4 ) - 1 \cdot x}{( x + 4 ) ^{2}} : \frac{20}{( x + 4 ) ^{2}}

= \frac{20}{( x + 4 ) ^{2}}

\int (\frac{1}{1 + x}) d x

f (x) = e^{- a x} cos (b x - c)

\int_{- 2}^{3} \frac{46}{x ^{4}} d x

x (- \frac{1}{5})

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