4 x^{3} y (x)^{5} + 5 y (x)^{4} \frac{d}{d x} (y (x)) x^{4} + 2 m (3 x^{2} y (x) + \frac{d}{d x} (y (x)) x^{3}) - 12 a y (x)^{2} \frac{d}{d x} (y (x))

Schritte zur Lösung

\frac{d}{d x} (x^{4} y (x)^{5} + 2 x m y (x) (x)^{2} - 4 y (x)^{3} a)

Vereinfache

x^{4} y (x)^{5} + 2 x m y (x) (x)^{2} - 4 y (x)^{3} a : x^{4} y (x)^{5} + 2 m x^{3} y (x) - 4 a y (x)^{3}

= \frac{d}{d x} (x^{4} y (x)^{5} + 2 m x^{3} y (x) - 4 a y (x)^{3})

Wende die Summen-/Differenzregel an:

(f \pm g)^{'} = f^{'} \pm g^{'}

= \frac{d}{d x} (x^{4} y (x)^{5}) + \frac{d}{d x} (2 m x^{3} y (x)) - \frac{d}{d x} (4 a y (x)^{3})

\frac{d}{d x} (x^{4} y (x)^{5}) = 4 x^{3} y (x)^{5} + 5 y (x)^{4} \frac{d}{d x} (y (x)) x^{4}

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

\frac{d}{d x} (4 a y (x)^{3}) = 12 a y (x)^{2} \frac{d}{d x} (y (x))

= 4 x^{3} y (x)^{5} + 5 y (x)^{4} \frac{d}{d x} (y (x)) x^{4} + 2 m (3 x^{2} y (x) + \frac{d}{d x} (y (x)) x^{3}) - 12 a y (x)^{2} \frac{d}{d x} (y (x))

\int \frac{( 2 x + 4 )}{( x ^{2} + 5 x - 6 )} d x

\frac{d}{d x} ((x + y) (x - y))

\int \frac{2 x ^{2} - 3 x + 2}{x ^{3} - 3 x ^{2} + 2 x} d x

\int \frac{1}{2 x ^{2} + 8 x + 20} d x

\int 8^{x} d x
