\frac{d}{d x} (\frac{- x}{y})

- \frac{y - x \frac{d y}{d x}}{y ^{2}}

Solution steps

\frac{d}{d x} (\frac{- x}{y})

Simplify

\frac{- x}{y} : - \frac{x}{y}

= \frac{d}{d x} (- \frac{x}{y})

Take the constant out:

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

= - \frac{d}{d x} (\frac{x}{y})

Apply the Quotient Rule:

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

= - \frac{\frac{d x}{d x} y - \frac{d y}{d x} x}{y ^{2}}

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

= - \frac{1 \cdot y - \frac{d y}{d x} x}{y ^{2}}

Simplify

= - \frac{y - x \frac{d y}{d x}}{y ^{2}}

\frac{2}{x + 5}

(- 1, - 4), (5, - 4)

\frac{d}{d x} (4 x - 5 x^{\frac{7}{8}})

f (x) = 8 e^{x} + x, (0, 8)

\int_{1}^{e^{2}} \frac{ln ^{3} ( x ^{2} )}{x} d x
