derivative of

y = \frac{4 + x f ( x )}{x}

\frac{2 x ^{2} \frac{df}{d x} + x f ( x ) - 4}{2 x x}

Solution steps

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

Apply the Quotient Rule:

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

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

\frac{d}{d x} (4 + x f (x)) = x \frac{df}{d x} + f (x)

\frac{d}{d x} (x) = \frac{1}{2 x}

= \frac{( x \frac{df}{d x} + f ( x ) ) x - \frac{1}{2 x} ( 4 + x f ( x ) )}{( x ) ^{2}}

Simplify

\frac{( x \frac{df}{d x} + f ( x ) ) x - \frac{1}{2 x} ( 4 + x f ( x ) )}{( x ) ^{2}} : \frac{2 x ^{2} \frac{df}{d x} + x f ( x ) - 4}{2 x x}

= \frac{2 x ^{2} \frac{df}{d x} + x f ( x ) - 4}{2 x x}

\int x e^{- 2} + e x^{- 2} d x

\frac{\partial}{\partial z} (x y^{2} z^{3})

arctan (\frac{x - 1}{x + 1})

\int \frac{e ^{3 x}}{1 - 2 e ^{3 x}} d x

ln (sin (x))
