derivative of

\frac{1 - 4 t}{5 + t}

- \frac{21}{( 5 + t ) ^{2}}

Solution steps

\frac{d}{d t} (\frac{1 - 4 t}{5 + t})

Apply the Quotient Rule:

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

= \frac{\frac{d}{d t} ( 1 - 4 t ) ( 5 + t ) - \frac{d}{d t} ( 5 + t ) ( 1 - 4 t )}{( 5 + t ) ^{2}}

\frac{d}{d t} (1 - 4 t) = - 4

\frac{d}{d t} (5 + t) = 1

= \frac{( - 4 ) ( 5 + t ) - 1 \cdot ( 1 - 4 t )}{( 5 + t ) ^{2}}

Simplify

\frac{( - 4 ) ( 5 + t ) - 1 \cdot ( 1 - 4 t )}{( 5 + t ) ^{2}} : - \frac{21}{( 5 + t ) ^{2}}

= - \frac{21}{( 5 + t ) ^{2}}

\frac{3 s}{s ^{2} + 4}

x + 6 y = 8, x + 8 = y^{2}

\frac{d}{d x} (- \frac{y}{x + 2 y})

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

\int \frac{x ^{2}}{6 - x ^{3}} d x
