\frac{d}{d x} (\frac{sin ( 5 x )}{x})

\frac{5 x cos ( 5 x ) - sin ( 5 x )}{x ^{2}}

Solution steps

\frac{d}{d x} (\frac{sin ( 5 x )}{x})

Apply the Quotient Rule:

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

= \frac{\frac{d}{d x} ( sin ( 5 x ) ) x - \frac{d x}{d x} sin ( 5 x )}{x ^{2}}

\frac{d}{d x} (sin (5 x)) = cos (5 x) \cdot 5

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

= \frac{cos ( 5 x ) \cdot 5 x - 1 \cdot sin ( 5 x )}{x ^{2}}

Simplify

= \frac{5 x cos ( 5 x ) - sin ( 5 x )}{x ^{2}}
