derivative of

\frac{sin ( x )}{x ^{2}}

\frac{x cos ( x ) - 2 sin ( x )}{x ^{3}}

Solution steps

\frac{d}{d x} (\frac{sin ( x )}{x ^{2}})

Apply the Quotient Rule:

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

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

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

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

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

Simplify

\frac{cos ( x ) x ^{2} - 2 x sin ( x )}{( x ^{2} ) ^{2}} : \frac{x cos ( x ) - 2 sin ( x )}{x ^{3}}

= \frac{x cos ( x ) - 2 sin ( x )}{x ^{3}}

e^{2} + (sec (x) x)

\frac{d}{dd} (10 d)

\frac{d}{d t} (3 sin (314 t) + 4 cos (314 t))

(x^{18})^{x}

\frac{d}{d z} (\frac{( 3 z + 2 i )}{( 4 z - 5 i )})
