\frac{d}{d x} (\frac{x ^{4} + 36 x ^{2}}{( x ^{2} + 12 ) ^{2}})

\frac{24 x ( - x ^{2} + 36 )}{( x ^{2} + 12 ) ^{3}}

Solution steps

\frac{d}{d x} (\frac{x ^{4} + 36 x ^{2}}{( x ^{2} + 12 ) ^{2}})

Apply the Quotient Rule:

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

= \frac{\frac{d}{d x} ( x ^{4} + 36 x ^{2} ) ( x ^{2} + 12 ) ^{2} - \frac{d}{d x} ( ( x ^{2} + 12 ) ^{2} ) ( x ^{4} + 36 x ^{2} )}{( ( x ^{2} + 12 ) ^{2} ) ^{2}}

\frac{d}{d x} (x^{4} + 36 x^{2}) = 4 x^{3} + 72 x

\frac{d}{d x} ((x^{2} + 12)^{2}) = 4 x (x^{2} + 12)

= \frac{( 4 x ^{3} + 72 x ) ( x ^{2} + 12 ) ^{2} - 4 x ( x ^{2} + 12 ) ( x ^{4} + 36 x ^{2} )}{( ( x ^{2} + 12 ) ^{2} ) ^{2}}

Simplify

\frac{( 4 x ^{3} + 72 x ) ( x ^{2} + 12 ) ^{2} - 4 x ( x ^{2} + 12 ) ( x ^{4} + 36 x ^{2} )}{( ( x ^{2} + 12 ) ^{2} ) ^{2}} : \frac{24 x ( - x ^{2} + 36 )}{( x ^{2} + 12 ) ^{3}}

= \frac{24 x ( - x ^{2} + 36 )}{( x ^{2} + 12 ) ^{3}}

y = \frac{e ^{9 x} + e ^{- 9 x}}{x}

\int tan^{2} (4 x) d x

\int x x d x

\int_{- \infty}^{3} e^{0.0001 t} d t
