\frac{d}{d x} (- \frac{4 x}{y})

- \frac{4 ( y - x \frac{d y}{d x} )}{y ^{2}}

Solution steps

\frac{d}{d x} (- \frac{4 x}{y})

Take the constant out:

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

= - 4 \frac{d}{d x} (\frac{x}{y})

Apply the Quotient Rule:

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

= - 4 \cdot \frac{\frac{d x}{d x} y - \frac{d y}{d x} x}{y ^{2}}

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

= - 4 \cdot \frac{1 \cdot y - \frac{d y}{d x} x}{y ^{2}}

Simplify

- 4 \cdot \frac{1 \cdot y - \frac{d y}{d x} x}{y ^{2}} : - \frac{4 ( y - x \frac{d y}{d x} )}{y ^{2}}

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

\frac{\partial}{\partial z} (x sin (yz))

\int x arcsin (6 x) d x
