\frac{d}{d x} (\frac{e ^{x}}{9 e ^{x} + x ^{2}})

\frac{e ^{x} x ^{2} - 2 e ^{x} x}{( 9 e ^{x} + x ^{2} ) ^{2}}

Solution steps

\frac{d}{d x} (\frac{e ^{x}}{9 e ^{x} + x ^{2}})

Apply the Quotient Rule:

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

= \frac{\frac{d}{d x} ( e ^{x} ) ( 9 e ^{x} + x ^{2} ) - \frac{d}{d x} ( 9 e ^{x} + x ^{2} ) e ^{x}}{( 9 e ^{x} + x ^{2} ) ^{2}}

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

\frac{d}{d x} (9 e^{x} + x^{2}) = 9 e^{x} + 2 x

= \frac{e ^{x} ( 9 e ^{x} + x ^{2} ) - ( 9 e ^{x} + 2 x ) e ^{x}}{( 9 e ^{x} + x ^{2} ) ^{2}}

Expand

e^{x} (9 e^{x} + x^{2}) - (9 e^{x} + 2 x) e^{x} : e^{x} x^{2} - 2 e^{x} x

= \frac{e ^{x} x ^{2} - 2 e ^{x} x}{( 9 e ^{x} + x ^{2} ) ^{2}}

\int_{2}^{3} 3 d x

- x^{2} + 10 x - 16, 2 x - 4, 2, 8

- 5 x^{3} ln (x)

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

y (x + 3) + y^{^{'}} = 0, y (- 6) = 1
