derivative of

\frac{x ^{3}}{4 - x}

\frac{12 x ^{2} - 2 x ^{3}}{( 4 - x ) ^{2}}

Solution steps

\frac{d}{d x} (\frac{x ^{3}}{4 - x})

Apply the Quotient Rule:

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

= \frac{\frac{d}{d x} ( x ^{3} ) ( 4 - x ) - \frac{d}{d x} ( 4 - x ) x ^{3}}{( 4 - x ) ^{2}}

\frac{d}{d x} (x^{3}) = 3 x^{2}

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

= \frac{3 x ^{2} ( 4 - x ) - ( - 1 ) x ^{3}}{( 4 - x ) ^{2}}

Simplify

\frac{3 x ^{2} ( 4 - x ) - ( - 1 ) x ^{3}}{( 4 - x ) ^{2}} : \frac{12 x ^{2} - 2 x ^{3}}{( 4 - x ) ^{2}}

= \frac{12 x ^{2} - 2 x ^{3}}{( 4 - x ) ^{2}}

\frac{1}{4 x ^{2}}

f (x) = 50

y = x (4 x - 3)

\frac{d}{d t} (- 10 + 2.5 t)

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