\frac{\partial}{\partial x} (\frac{3 x}{x ^{2} + 2})

Entferne die Konstante:

(a \cdot f)^{'} = a \cdot f^{'}

= 3 \frac{\partial}{\partial x} (\frac{x}{x ^{2} + 2})

Wende die Quotientenregel an:

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

= 3 \cdot \frac{\frac{\partial}{\partial x} ( x ) x ^{2} + 2 - \frac{\partial}{\partial x} ( x ^{2} + 2 ) x}{( x ^{2} + 2 ) ^{2}}

\frac{\partial}{\partial x} (x) = 1

\frac{\partial}{\partial x} (x^{2} + 2) = \frac{x}{x ^{2} + 2}

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

Vereinfache

3 \cdot \frac{1 \cdot x ^{2} + 2 - \frac{x}{x ^{2} + 2} x}{( x ^{2} + 2 ) ^{2}} : \frac{6}{( x ^{2} + 2 ) x ^{2} + 2}

= \frac{6}{( x ^{2} + 2 ) x ^{2} + 2}

\frac{d}{d x} (8 x^{2} sin (x) tan (x))

\frac{d y}{d x} = \frac{y ^{2} - y}{x}

x^{2} y^{^{''}} - 4 x y^{^{'}} + 6 y = 0, y (1) = 0.4, y^{^{'}} (1) = 0

y^{^{'''}} - 7 y^{^{''}} + 8 y^{^{'}} + 16 y = 0
