\frac{x - 13}{x - 13}

\frac{x - 2 13 x + 13}{2 x ( x - 13 ) ^{2}}

Schritte zur Lösung

\frac{d}{d x} (\frac{x - 13}{x - 13})

Wende die Quotientenregel an:

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

= \frac{\frac{d}{d x} ( x - 13 ) ( x - 13 ) - \frac{d}{d x} ( x - 13 ) ( x - 13 )}{( x - 13 ) ^{2}}

\frac{d}{d x} (x - 13) = 1

\frac{d}{d x} (x - 13) = \frac{1}{2 x}

= \frac{1 \cdot ( x - 13 ) - \frac{1}{2 x} ( x - 13 )}{( x - 13 ) ^{2}}

Vereinfache

\frac{1 \cdot ( x - 13 ) - \frac{1}{2 x} ( x - 13 )}{( x - 13 ) ^{2}} : \frac{x - 2 13 x + 13}{2 x ( x - 13 ) ^{2}}

= \frac{x - 2 13 x + 13}{2 x ( x - 13 ) ^{2}}

(6 x + 1) y^{2} \frac{d y}{d x} + 4 x^{2} + 2 y^{3} = 0

\frac{\partial}{\partial x} (y x^{2} z^{2} - x y^{4} + x z)

\frac{d}{d x} (ln (x) cos (x))

x^{2} y^{^{''}} + 3 x y^{^{'}} - 15 y = 0
